Debian LTS: DLA-2222-1: libexif security update
Summary
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.
