high Nessus Plugin ID 346798

Synopsis

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

Description

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:4200-1 advisory.

- CVE-2026-84267: `read_string()` allocates buffers withouth verifying that the buffer is completely filled when communicating with a malicious SFTP server, which can lead to uninitialized heap memory leaks (bsc#1278157).
- CVE-2026-84268: `read_reply()` processes length that exceeds requested client size when communicating with a malicious SFTP server, which can lead to an OOB write (bsc#1278158).
- CVE-2026-84269: DSI read path processes length that exceeds requested client size when communicating with a malicious AFP server, which can lead to an OOB memory access (bsc#1278159).
- CVE-2026-84270: `do_read()` trusts the data length returned by a mounted MTP device and does not limit it to the original size requested by the client, which can lead to an OOB write (bsc#1278156).

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
