Buffer Overflow vulnerability in function bitwriter_grow_ in flac before 1.4.0 allows remote attackers to run arbitrary code via crafted input to the encoder.

Vulnerabilidad de Desbordamiento de Búfer en la función bitwriter_grow_ en flac anterior a 1.4.0 permite a atacantes remotos ejecutar código arbitrario a través de una entrada manipulada al codificador.

A flaw was found in the libeconf library. This issue occurs due to a buffer overflow vulnerability in the bitwriter_grow_ function in FLAC that allows remote attackers to run arbitrary code via crafted input to the encoder.

USN-6360-1 fixed a vulnerability in FLAC. This update provides the corresponding update for Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, and Ubuntu 18.04 LTS. It was discovered that FLAC incorrectly handled encoding certain files. A remote attacker could use this issue to cause FLAC to crash, resulting in a denial of service, or possibly execute arbitrary code.
