Debian DLA-2439-1 : libexif security update

critical Nessus Plugin ID 142623

Language:

Synopsis

The remote Debian host is missing a security update.

Description

In libexif/exif-entry.c, through libexif 0.6.21-2+deb9u4, compiler optimization could remove a buffer overflow check, making a buffer overflow possible with some EXIF tags.

For Debian 9 stretch, this problem has been fixed in version 0.6.21-2+deb9u5.

We recommend that you upgrade your libexif packages.

For the detailed security status of libexif please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/libexif

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.
