Vulnerability details
The vulnerability allows a remote attacker to exhaust memory and cause a denial of service.
The vulnerability exists due to decompression without an output-size limit in getID3's getid3_id3v2::ParseID3v2Frame() when processing compressed ID3v2 frames. A remote attacker can upload a small file containing a highly compressed frame to an application that analyzes attacker-supplied files, triggering excessive allocation through gzuncompress() to terminate PHP workers and disrupt service.
