 Package : libexif Version : 0.6.22-3+deb11u1 CVE ID : CVE-2026-32775 CVE-2026-40385 CVE-2026-40386 Debian Bug : 1131116 1133922 1133923

 Three security vulnerabilities were discovered in libexif, a library to reads and writes EXIF metainformation from and to images files, that can causes crashes or information leaks.

 CVE-2026-32775

 If the exif_mnote_data_get_value function in MakerNotes gets passed in a 0 size, the passed in-buffer would be overwritten due to an integer underflow.

 CVE-2026-40385

 An unsigned 32bit integer overflow in Nikon MakerNote handling could be used by local attackers to cause crashes or information leaks.

 CVE-2026-40386

 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.

 For Debian 11 bullseye, these problems have been fixed in version 0.6.22-3+deb11u1.

 We recommend that you upgrade your libexif packages.
