USN-5483-1: Exempi vulnerabilities

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 stop responding 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 22.04

• libexempi8 - 2.5.2-1ubuntu0.22.04.1
• exempi - 2.5.2-1ubuntu0.22.04.1

Ubuntu 21.10

• libexempi8 - 2.5.2-1ubuntu0.21.10.1
• exempi - 2.5.2-1ubuntu0.21.10.1

Ubuntu 20.04

• libexempi8 - 2.5.1-1ubuntu0.1
• exempi - 2.5.1-1ubuntu0.1

Ubuntu 18.04

• exempi - 2.4.5-2ubuntu0.1
• libexempi3 - 2.4.5-2ubuntu0.1

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