high Nessus Plugin ID 379477

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:5181-1 advisory.

- Authenticated SFTP sessions can overflow the SFTP packet buffer (bsc#1271096).
- CVE-2026-35025: access control bypass allows authenticated FTP users to circumvent Directory ACL restrictions by prefixing paths with `/proc/self/root` in the RNFR command handler (bsc#1269065).
- CVE-2026-42167: `mod_sql` allows remote attackers to execute arbitrary code via a username when there is logging of `USER` requests with an expansion such as `%U` and the SQL backend allows `comman` (bsc#1263183).
- CVE-2026-44331: SQL injection in `sqltab_fetch_clients_cb()` in `contrib/mod_wrap2_sql.c` triggered via crafted domain name from reverse DNS lookup (bsc#1264262).
- CVE-2026-53994: heap-based buffer overflow reachable by an authenticated SFTP user can lead to denial of service and memory corruption (bsc#1271946).
- CVE-2026-63090: heap-based buffer overflow in the `mod_sftp` module can lead to arbitrary code execution via crafted SFTP packet fragments (bsc#1271944).
- CVE-2026-63091: signed integer overflow in the `mod_sftp` module's SCP size-record parser can lead to ASLR bypass via a crafted file size value of `UINT64_MAX` (bsc#1271945).
- CVE-2026-119147: authorization bypass in the `mod_sftp` copy-file extension handler allows SFTP users to copy any readable file to a new path in write-denied directories (bsc#1289272).
- Integer overflow via client-provided file size for SCP uploads (bsc#1271097).

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.

Solution

Update the affected packages.
