"tixxDZ (DZCORE labs) discovered a vulnerability in vlc, the multimedia
player and streamer. Missing data validation in vlc's real data
transport (RDT) implementation enable an integer underflow and
consequently an unbounded buffer operation. A maliciously crafted
stream could thus enable an attacker to execute arbitrary code.

No Common Vulnerabilities and Exposures project identifier is
available for this issue."
