high Nessus Plugin ID 175058

Language:

Description

The remote host is affected by the vulnerability described in GLSA-202305-21 (Cairo: Buffer Overflow Vulnerability)

 - A flaw was found in cairo's image-compositor.c in all versions prior to 1.17.4. This flaw allows an attacker who can provide a crafted input file to cairo's image-compositor (for example, by convincing a user to open a file in an application using cairo, or if an application uses cairo on untrusted input) to cause a stack buffer overflow -> out-of-bounds WRITE. The highest impact from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2020-35492)

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

Solution

All Cairo users should upgrade to the latest version:

 # emerge --sync # emerge --ask --oneshot --verbose >=x11-libs/cairo-1.17.6
