Cross-zone scripting vulnerability in the NowPlaying functionality in NullSoft Winamp before 5.541 allows remote attackers to conduct cross-site scripting (XSS) attacks via an MP3 file with JavaScript in id3 tags.

Nullsoft Winamp before 5.24 does not properly verify the authenticity of updates, which allows man-in-the-middle attackers to execute arbitrary code via a Trojan horse update, as demonstrated by evilgrade and DNS cache poisoning.

Multiple stack-based buffer overflows in in_mp3.dll in Winamp 5.21, 5.5, and 5.51 allow remote attackers to execute arbitrary code via a long (1) artist or (2) name tag in Ultravox streaming metadata, related to construction of stream titles.

Stack-based buffer overflow in Nullsoft Winamp 5.32 allows user-assisted remote attackers to execute arbitrary code via crafted unicode in a .mp4 file, with crafted tags, contained in a certain .rar archive, a related issue to CVE-2007-2498. NOTE: for exploitation, the victim must select a certain menu option at the time of the attack.

Multiple integer overflows in Free Lossless Audio Codec (FLAC) libFLAC before 1.2.1, as used in Winamp before 5.5 and other products, allow user-assisted remote attackers to execute arbitrary code via a malformed FLAC file that triggers improper memory allocation, resulting in a heap-based buffer overflow.

The mIRC Control Plug-in for Winamp allows user-assisted remote attackers to execute arbitrary code via the '|' (pipe) shell metacharacter in the name of the song in a .mp3 file.

Winamp 5.35 allows remote attackers to cause a denial of service (program stack overflow and application crash) via an M3U file that recursively includes itself.

libmp4v2.dll in Winamp 5.02 through 5.34 allows user-assisted remote attackers to execute arbitrary code via a certain .MP4 file. NOTE: some of these details are obtained from third party information.

Buffer overflow in Nullsoft Winamp 5.3 allows user-assisted remote attackers to cause a denial of service (crash) via a crafted WMV file.

The Impulse Tracker (IT) and ScreamTracker 3 (S3M) modules in IN_MOD.DLL in AOL Nullsoft Winamp 5.33 allows remote attackers to execute arbitrary code via a crafted (1) .IT or (2) .S3M file containing integer values that are used as memory offsets, which triggers memory corruption.
