A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 17.10 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS


Exempi could be made to crash or run programs if it opened a specially crafted file.

Software Description: - exempi: library to parse XMP metadata


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.
