Debian DLA-2974-1 : fribidi - LTS security update

high Nessus Plugin ID 159762

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2974 advisory.

- 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)

- 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)

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

Solution

Upgrade the fribidi packages.

For Debian 9 stretch, these problems have been fixed in version 0.19.7-1+deb9u2.
