SYNTHESIS OF THE VULNERABILITY

An attacker can generate a buffer overflow of LZ4 Core, in order
to trigger a denial of service, and possibly to execute code.

Impacted products: Fedora, Linux, Unix (platform)

Severity: 2/4

Creation date: 03/07/2014

DESCRIPTION OF THE VULNERABILITY

The LZ4 Core library implements the LZ4 compression algorithm.

However, if the size of data is greater than the size of the
storage array, an overflow occurs.

An attacker can therefore generate a buffer overflow of LZ4 Core,
in order to trigger a denial of service, and possibly to execute
code.
