Description

This security bulletin contains information about 1 vulnerability.


1) Improper handling of highly compressed data (CVE-ID: N/A)

CWE-ID: CWE-409 - Improper Handling of Highly Compressed Data (Data Amplification)

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


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.
