Description
The parseRTSPRequestString function in Live Networks Live555 Streaming Media 2011.08.13 through 2013.11.25, as used in VideoLAN VLC Media Player, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a (1) space or (2) tab character at the beginning of an RTSP message, which triggers an integer underflow, infinite loop, and buffer overflow.
Exploitation
Not listed in the CISA Known Exploited Vulnerabilities catalogue as of 2026.09.04. That is an absence of confirmed public exploitation, not evidence that exploitation has not occurred.
