The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:21252-1 advisory.

    Update to version 1.5.3.

    Security issues fixed:

    - CVE-2026-20213: out-of-bounds write due to improper boundary checks for content in PE files during     scanning       (bsc#1270107).
    - CVE-2026-20214: out-of-bounds write due to improper boundary checks for content in FSG files during     scanning       (bsc#1270085).
    - CVE-2026-20215: out-of-bounds write due to improper boundary checks for content in 7z files during     scanning       (bsc#1270088).
    - CVE-2026-20216: denial of service due to improper handling of temporary resources during InstallShield     file scanning       (bsc#1270089).
    - CVE-2026-20217: out-of-bounds write due to improper boundary checks for content in PESpin files during     scanning       (bsc#1270091).
    - CVE-2026-20243: out-of-bounds write due to improper boundary checks for content in ALZ files during     scanning       (bsc#1270092).
    - CVE-2026-20244: integer overflow and DoS due to improper boundary checks for content in DMG files during     scanning       (bsc#1270106).
    - CVE-2026-41676: buffer overflow due to missing checks via `Deriver:derive`, `PkeyCtxRef:derive` and     OpenSSL 1.1.1       (bsc#1270138).

    Other updates and bugfixes:

    - Version 1.5.3:
     * Fixed a bug in the PESpin unpacker cleanup path that could free pointers into the scanned file buffer     and crash the        scanner.
     * Fixed an integer overflow in PE rebuild size calculations that could be reached through a malformed     Aspack-packed PE        file and lead to a heap buffer overflow write.
     * Fixed an InstallShield archive extraction limit bypass that could write far more temporary data than     intended and        exhaust temporary storage.
     * Fixed an FSG unpacker loop underflow that could write past the section array while scanning a malformed     PE file.
     * Fixed ALZ parser size handling bugs that could cause malformed ALZ archives to panic, abort the     scanner, or skip        expected scan-limit handling.
     * Fixed a 7z parser substream count overflow that could under-allocate parser metadata arrays and write     past them        while reading a malformed archive.
     * Fixed 32-bit DMG parser size checks that could let a short mish stripe table pass validation and crash     32-bit        scanner builds.
     * Hardened clamscan, clamdscan, and clamonacc quarantine actions against time-of-check/time-of-use races     that could        redirect copied, moved, or removed files under unsafe quarantine directory configurations.
     * Upgraded the Rust tar dependency to resolve the RUSTSEC-2026-0067 and RUSTSEC-2026-0068 advisories, and     upgraded the        Rust openssl dependency to resolve CVE-2026-41676.
     * Raised the minimum required CMake version to 3.17 to fix Linux builds with libcurl v8.21.0 when linking     static        library dependencies.
     * Metadata preclass scans now run before the final scan verdict.
     * ClamOnAcc: Fixed errors when recursively excluded paths are children of an included path.
     * ClamOnAcc: Fixed hash bucket list corruption when two watched paths collide in the same bucket.
