Debian DLA-2222-1 : libexif security update

critical Nessus Plugin ID 136952

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Various minor vulnerabilities have been addredd in libexif, a library to parse EXIF metadata files.

CVE-2018-20030

This issue had already been addressed via DLA-2214-1. However, upstream provided an updated patch, so this has been followed up on.

CVE-2020-13112

Several buffer over-reads in EXIF MakerNote handling could have lead to information disclosure and crashes. This issue is different from already resolved CVE-2020-0093.

CVE-2020-13113

Use of uninitialized memory in EXIF Makernote handling could have lead to crashes and potential use-after-free conditions.

CVE-2020-13114

An unrestricted size in handling Canon EXIF MakerNote data could have lead to consumption of large amounts of compute time for decoding EXIF data.

For Debian 8 'Jessie', these problems have been fixed in version 0.6.21-2+deb8u3.

We recommend that you upgrade your libexif packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected libexif-dev, and libexif12 packages.
