A flaw was found in libsolv. This heap buffer overflow vulnerability occurs when a victim processes a specially crafted `.solv` file containing negative size values in the `repo_add_solv` function. This leads to an undersized memory allocation and a subsequent out-of-bounds write. An attacker could exploit this to cause a denial of service (DoS).

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:2674-1 advisory.

    This update for libsolv, libzypp, zypper fixes the following issues

    - CVE-2026-9149: Heap buffer overflow in libsolv repo_add_solv via negative maxsize from crafted .solv     file       (bsc#1265935).
    - CVE-2026-9150: Stack-based buffer overflow in libsolv's Debian metadata parser when handling     SHA384/SHA512 checksums       (bsc#1265938).
    - CVE-2026-25707: Handcrafted repo metadata may cause arbitrary local files to be overwritten     (bsc#1259802).
    - CVE-2026-44933: scan of the Mandatory signature verification plugin support (bsc#1265223).
    - CVE-2026-44941: path traversal via 'keyhint' (bsc#1267426).
    - CVE-2026-44942: .repo files can have an optional path which can lead to path traversal attacks     (bsc#1267874).
    - CVE-2026-48863: Fix buffer overflow when parsing EdDSA signature (bsc#1266039).

    Changes in libzypp:

    Updated to version 17.38.13 (35):

    - A .repo files 'path=' entry must not refer to a location       outside the repo (bsc#1267874, CVE-2026-44942)       A 'path=' entry may solely denote a sub-directory of the baseurl       where the metadata are located. A relative path trying to access       data outside the baseurl is reported and sanitized.
    - Fix potential crash on malformed or malicious repository       metadata (fixes #740)
    - Repo metadata: discard entries referring to a location outside       the repo (bsc#1259802, CVE-2026-25707)       Mirroring those data locally would refer to a location outside       the repo's local cache directory. Those data entries are reported       and discarded.
    - zypp.conf: Allow [env] section to add environment variables.
      This feature is designed to enable environment-specific settings       or debugging options over an extended period. See zypp.conf(5).
    - Prevent configured scripts from escaping the sigcheck directory       (bsc#1265223, CVE-2026-44933)
    - StringV: guard hasPrefix/hasPrefixCI against reading past the       view end (fixes #735)
    - Mandatory signature verification plugin support (PED#11922)
    - Fix purge-kernel -rc kernel handling (bsc#1239718)
    - Explicitly_set_pool_DISTTYPE_RPM (fixes #726)
    - Check for trusted key updates when updating the general keyring       (bsc#1259706)
    - Support multiple MirroredOrigin authorities (bsc#1253193)
    - Workaround doxygen bug: doxygen/doxygen#12057
    - libzypp.spec: Add missing graphviz-gd BuildRequires (boo#1259842)
    - Fix preloader not caching packages from arch specific subrepos       (bsc#1253740)
    - Deprioritize invalid mirrors (fixes openSUSE/zypper#636)
    - Fix Product::referencePackage lookup (bsc#1259311)       Use a provided autoproduct() as hint to the package name of the       release package. It might be that not just multiple versions of       the same release package provide the same product version, but       also different release packages.
    - specfile: on fedora use %{_prefix}/share as zyppconfdir if       %{_distconfdir} is undefined (fixes #693)       This will set '-DZYPPCONFDIR=%{zyppconfdir}' for cmake.
    - Fall back to a writable location when precaching packages       without root (bsc#1247948)
    - Prepare a legacy /etc/zypp/zypp.conf to be installed on old distros.
      See the ZYPP.CONF(5) man page for details.
    - Fix runtime check for broken rpm --runposttrans (bsc#1257068)
    - Avoid libcurl-mini4 when building as it does not support ftp       protocol.
    - Translation: updated .pot file.
    - zypp.conf: follow the UAPI configuration file specification       (PED-14658)       In short terms it means we will no longer ship an       /etc/zypp/zypp.conf, but store our own defaults in       /usr/etc/zypp/zypp.conf. The systems administrator may choose to       keep a full copy in /etc/zypp/zypp.conf ignoring our config file       settings completely, or - the preferred way - to overwrite       specific settings via /etc/zypp/zypp.conf.d/*.conf overlay files.
      See the ZYPP.CONF(5) man page for details.
    - cmake: correctly detect rpm6 (fixes #689)
    - Use 'zypp.tmp' as temp directory component to ease setting up       SELinux policies (bsc#1249435)
    - zyppng: Update Provider to current MediaCurl2 download       approach, drop Metalink ( fixes #682 )

    Changes in libsolv:

    Updated to version 0.7.39:

    - fix solv_chksum_free segfault when called with a NULL pointer
    - made repo_add_solv more robust against corrupt files       [bsc#1265935] [CVE-2026-9149]
    - fix potential buffer overflow when verifying EdDSA signatures       [bsc#1266039] [CVE-2026-48863]
    - added limit checks in multiple places to catch overflows
    - reduce the size of the language id cache
    - fixed Debian canon selection
    - fixed dbpath detection in repo_rpmdb_librpm
    - reduced stack usage in repo page compression (needed for musl)
    - fix parsing of sha512 checksums in debian repositories       [bsc#1265938] [CVE-2026-9150]
    - improve speed of dirpool_add_dir makeing parsing of filelists.xml       twice as fast
    - fix parsing of recommends in the old Mandriva synthesis format
    - respect the 'default' attribute in environment optionlist in       the comps parser
    - support suse namespace deps in boolean dependencies [bsc#1258193]
    - support for the Elbrus2000 (e2k) architecture
    - support language() suse namespace rewriting

    Changes in zypper:

    Update to version 1.14.98:

    - Transactional systems: Delegate rw-commands to       transactional-wrapper if available (jsc#PED-13680, jsc#PED-15607)       On a transactional system where the root filesystem is mounted       read-only, zypper commands that modify the system cannot be       executed directly.
      If the system provides a transactional-wrapper utility, zypper       will automatically attempt to invoke it. The wrapper       transparently executes the zypper command within a new, writable       snapshot and manages the lifecycle of that snapshot based on the       command's exit status.
      On transactional systems lacking a transactional-wrapper, users       must manually invoke specialized tools -such as       transactional-update- to install, update, or remove software.
    - Add --filter-version-change to zypper lu.
      Adds filtering by version change significance to reduce noise in       update listings. Supports levels: rebuild (hides rebuild-only       changes) and package (hides all release-only changes).
    - Autorefresh ris-services the way as plugin-services (bsc#1246504)       It's actually wrong to treat service refreshes different       depending on the service type. For the purpose of a service it       makes no difference how the data about the repos to use are       acquired.
    - Report download progress for command line rpms (fixes #613)
    - Hint to '-vv ref' to see the mirrors used to download the       metadata (bsc#1257882)
    - Service: Allow 'zypper ls SERVICE ...' to test whether a       service with this alias is defined (bsc#1252744)       The command prints an abstract of all services passed on the       command line. It returns 3-ZYPPER_EXIT_ERR_INVALID_ARGS if some       argument does not name an existing service.
    - Keep repo data when updating the service settings (bsc#1252744)
    - info: Enhance pattern content table (bsc#1158038)       Alternatives (multiple packages providing the same requirement)       are now listed as a single entry in the content table. The entry       shows either the installed package which satisfies the       requirement or the requirement itself as type 'Provides'.
      Listing all potential alternatives was miss leading, especially       if the alternatives were mutual exclusive. It looked like an       installed pattern had not-installed requirements and it was not       possible to install all requirements at the same time.

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

    This update for libsolv, libzypp, zypper fixes the following issues

    - CVE-2026-9149: Heap buffer overflow in libsolv repo_add_solv via negative maxsize from crafted .solv     file       (bsc#1265935).
    - CVE-2026-9150: Stack-based buffer overflow in libsolv's Debian metadata parser when handling     SHA384/SHA512 checksums       (bsc#1265938).
    - CVE-2026-25707: Handcrafted repo metadata may cause arbitrary local files to be overwritten     (bsc#1259802).
    - CVE-2026-44933: scan of the Mandatory signature verification plugin support (bsc#1265223).
    - CVE-2026-44941: path traversal via 'keyhint' (bsc#1267426).
    - CVE-2026-44942: .repo files can have an optional path which can lead to path traversal attacks     (bsc#1267874).
    - CVE-2026-48863: Fix buffer overflow when parsing EdDSA signature (bsc#1266039).

    Changes in libzypp:

    Updated to version 17.38.13 (35):

    - A .repo files 'path=' entry must not refer to a location       outside the repo (bsc#1267874, CVE-2026-44942)       A 'path=' entry may solely denote a sub-directory of the baseurl       where the metadata are located. A relative path trying to access       data outside the baseurl is reported and sanitized.
    - Fix potential crash on malformed or malicious repository       metadata (fixes #740)
    - Repo metadata: discard entries referring to a location outside       the repo (bsc#1259802, CVE-2026-25707)       Mirroring those data locally would refer to a location outside       the repo's local cache directory. Those data entries are reported       and discarded.
    - zypp.conf: Allow [env] section to add environment variables.
      This feature is designed to enable environment-specific settings       or debugging options over an extended period. See zypp.conf(5).
    - Prevent configured scripts from escaping the sigcheck directory       (bsc#1265223, CVE-2026-44933)
    - StringV: guard hasPrefix/hasPrefixCI against reading past the       view end (fixes #735)
    - Mandatory signature verification plugin support (PED#11922)
    - Fix purge-kernel -rc kernel handling (bsc#1239718)
    - Explicitly_set_pool_DISTTYPE_RPM (fixes #726)
    - Check for trusted key updates when updating the general keyring       (bsc#1259706)
    - Support multiple MirroredOrigin authorities (bsc#1253193)
    - Workaround doxygen bug: doxygen/doxygen#12057
    - libzypp.spec: Add missing graphviz-gd BuildRequires (boo#1259842)
    - Fix preloader not caching packages from arch specific subrepos       (bsc#1253740)
    - Deprioritize invalid mirrors (fixes openSUSE/zypper#636)
    - Fix Product::referencePackage lookup (bsc#1259311)       Use a provided autoproduct() as hint to the package name of the       release package. It might be that not just multiple versions of       the same release package provide the same product version, but       also different release packages.
    - specfile: on fedora use %{_prefix}/share as zyppconfdir if       %{_distconfdir} is undefined (fixes #693)       This will set '-DZYPPCONFDIR=%{zyppconfdir}' for cmake.
    - Fall back to a writable location when precaching packages       without root (bsc#1247948)
    - Prepare a legacy /etc/zypp/zypp.conf to be installed on old distros.
      See the ZYPP.CONF(5) man page for details.
    - Fix runtime check for broken rpm --runposttrans (bsc#1257068)
    - Avoid libcurl-mini4 when building as it does not support ftp       protocol.
    - Translation: updated .pot file.
    - zypp.conf: follow the UAPI configuration file specification       (PED-14658)       In short terms it means we will no longer ship an       /etc/zypp/zypp.conf, but store our own defaults in       /usr/etc/zypp/zypp.conf. The systems administrator may choose to       keep a full copy in /etc/zypp/zypp.conf ignoring our config file       settings completely, or - the preferred way - to overwrite       specific settings via /etc/zypp/zypp.conf.d/*.conf overlay files.
      See the ZYPP.CONF(5) man page for details.
    - cmake: correctly detect rpm6 (fixes #689)
    - Use 'zypp.tmp' as temp directory component to ease setting up       SELinux policies (bsc#1249435)
    - zyppng: Update Provider to current MediaCurl2 download       approach, drop Metalink ( fixes #682 )

    Changes in libsolv:

    Updated to version 0.7.39:

    - fix solv_chksum_free segfault when called with a NULL pointer
    - made repo_add_solv more robust against corrupt files       [bsc#1265935] [CVE-2026-9149]
    - fix potential buffer overflow when verifying EdDSA signatures       [bsc#1266039] [CVE-2026-48863]
    - added limit checks in multiple places to catch overflows
    - reduce the size of the language id cache
    - fixed Debian canon selection
    - fixed dbpath detection in repo_rpmdb_librpm
    - reduced stack usage in repo page compression (needed for musl)
    - fix parsing of sha512 checksums in debian repositories       [bsc#1265938] [CVE-2026-9150]
    - improve speed of dirpool_add_dir makeing parsing of filelists.xml       twice as fast
    - fix parsing of recommends in the old Mandriva synthesis format
    - respect the 'default' attribute in environment optionlist in       the comps parser
    - support suse namespace deps in boolean dependencies [bsc#1258193]
    - support for the Elbrus2000 (e2k) architecture
    - support language() suse namespace rewriting

    Changes in zypper:

    Update to version 1.14.98:

    - Transactional systems: Delegate rw-commands to       transactional-wrapper if available (jsc#PED-13680, jsc#PED-15607)       On a transactional system where the root filesystem is mounted       read-only, zypper commands that modify the system cannot be       executed directly.
      If the system provides a transactional-wrapper utility, zypper       will automatically attempt to invoke it. The wrapper       transparently executes the zypper command within a new, writable       snapshot and manages the lifecycle of that snapshot based on the       command's exit status.
      On transactional systems lacking a transactional-wrapper, users       must manually invoke specialized tools -such as       transactional-update- to install, update, or remove software.
    - Add --filter-version-change to zypper lu.
      Adds filtering by version change significance to reduce noise in       update listings. Supports levels: rebuild (hides rebuild-only       changes) and package (hides all release-only changes).

An update of the libsolv package has been released.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1798 advisory.

    A flaw was found in libsolv. A stack-based buffer overflow vulnerability exists in the PGP verification     component due to incorrect length handling when copying EdDSA 's' MPI into a stack buffer. A remote     attacker could craft a malicious Ed25519 PGP signature with mismatched MPI lengths. Processing this     crafted signature could lead to a denial of service in automated package or repository processing     workflows. (CVE-2026-48863)

    A flaw was found in libsolv. This heap buffer overflow occurs during the decompression of attacker-     controlled compressed data within `.solv` files due to insufficient input validation. An attacker can     provide a specially crafted `.solv` file, which, when processed by a vulnerable application, can lead to     out-of-bounds memory access. This could result in information disclosure, alteration of program execution,     or a denial of service. (CVE-2026-48864)

    A flaw was found in libsolv. This heap buffer overflow vulnerability occurs when a victim processes a     specially crafted .solv file containing negative size values in the repo_add_solv function. This leads to     an undersized memory allocation and a subsequent out-of-bounds write. An attacker could exploit this to     cause a denial of service (DoS). (CVE-2026-9149)

    A flaw was found in libsolv. This stack-based buffer overflow vulnerability occurs in libsolv's Debian     metadata parser when processing specially crafted Debian repository metadata. An attacker could exploit     this by providing malicious SHA384 or SHA512 checksum tags, leading to memory corruption and a denial of     service (DoS) in the affected system. (CVE-2026-9150)
