Ubuntu Security Notice USN-3668-1

exempi vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- - Ubuntu 17.10
- - Ubuntu 16.04 LTS
- - Ubuntu 14.04 LTS
Summary:
Exempi could be made to crash or run programs if it opened a specially
crafted file.
Software Description:
- - 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 LTS:
exempi 2.2.2-2ubuntu0.1
libexempi3 2.2.2-2ubuntu0.1
Ubuntu 14.04 LTS:
exempi 2.2.1-1ubuntu1.1
libexempi3 2.2.1-1ubuntu1.1
In general, a standard system update will make all the necessary changes.
