CentOS Linux 7 [TuxCare] Security Update: libexif / libexif-devel / libexif-doc Multiple Vulnerabilities (CENTOS7:CLSA-2026:1776791358)

high Nessus Plugin ID 359872

Synopsis

The CentOS Linux host is missing one or more security updates.

Description

The CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS7:CLSA-2026:1776791358 advisory.

 - libexif through 0.6.25 has a flaw in decoding MakerNotes. If the exif_mnote_data_get_value function gets passed in a 0 size, the passed in-buffer would be overwritten due to an integer underflow.
 (CVE-2026-32775)

 - In libexif through 0.6.25, an unsigned 32bit integer overflow in Nikon MakerNote handling could be used by local attackers to cause crashes or information leaks. This only affects 32bit systems. (CVE-2026-40385)

 - In libexif through 0.6.25, an integer underflow in size checking for Fuji and Olympus MakerNote decoding could be used by attackers to crash or leak information out of libexif-using programs. (CVE-2026-40386)

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 packages based on the guidance in TuxCare advisory CENTOS7:CLSA-2026:1776791358.
