USN-3668-1: Exempi vulnerabilities

Releases

• Ubuntu 17.10
• Ubuntu 16.04 ESM
• Ubuntu 14.04 ESM

Packages

• exempi - library to parse XMP metadata

Details

It was discovered that Exempi incorrectly handled certain media files. If a
user or automated system were tricked into opening a specially crafted
file, a remote attacker could cause Exempi to hang or crash, resulting in a
denial of service, or possibly execute arbitrary code.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 17.10

• exempi - 2.4.3-1ubuntu1.1
• libexempi3 - 2.4.3-1ubuntu1.1

Ubuntu 16.04

• exempi - 2.2.2-2ubuntu0.1
• libexempi3 - 2.2.2-2ubuntu0.1

Ubuntu 14.04

• exempi - 2.2.1-1ubuntu1.1
• libexempi3 - 2.2.1-1ubuntu1.1

In general, a standard system update will make all the necessary changes.
