Synopsis

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

Description

The remote Ubuntu 16.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5922-1 advisory.

 - A stack-based buffer overflow flaw was found in the Fribidi package. This flaw allows an attacker to pass a specially crafted file to the Fribidi application, which leads to a possible memory leak or a denial of service. (CVE-2022-25308)

 - A heap-based buffer overflow flaw was found in the Fribidi package and affects the fribidi_cap_rtl_to_unicode() function of the fribidi-char-sets-cap-rtl.c file. This flaw allows an attacker to pass a specially crafted file to the Fribidi application with the '--caprtl' option, leading to a crash and causing a denial of service. (CVE-2022-25309)

 - A segmentation fault (SEGV) flaw was found in the Fribidi package and affects the fribidi_remove_bidi_marks() function of the lib/fribidi.c file. This flaw allows an attacker to pass a specially crafted file to Fribidi, leading to a crash and causing a denial of service. (CVE-2022-25310)

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 libfribidi-bin, libfribidi-dev and / or libfribidi0 packages.
