Language:

Description

The remote host is affected by the vulnerability described in GLSA-202309-04 (RAR, UnRAR: Arbitrary File Overwrite)

- RARLAB UnRAR before 6.12 on Linux and UNIX allows directory traversal to write to files during an extract (aka unpack) operation, as demonstrated by creating a ~/.ssh/authorized_keys file. NOTE: WinRAR and Android RAR are unaffected. (CVE-2022-30333)

- The vulnerability exists due to improper validation of array index when processing recovery volumes. A remote attacker can trick the victim to open a specially crafted archive and execute arbitrary code on the system. (CVE-2023-40477)

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

Solution

All RAR users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose >=app-arch/rar-6.23 All UnRAR users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose >=app-arch/unrar-6.2.10
