Nullsoft Scriptable Install System (NSIS) before 3.11 on Windows allows local users to escalate privileges to SYSTEM during an installation, because the temporary plugins directory is created under %WINDIR%\temp and unprivileged users can place a crafted executable file by winning a race condition. This occurs because EW_CREATEDIR does not always set the CreateRestrictedDirectory error flag.

Low IL Temp Directory Path Exposure Allows Local Privilege Escalation

NSIS (Nullsoft Scriptable Install System) 3.06.1 before 3.12 sometimes uses the Low IL temp directory when executing as SYSTEM, allowing local attackers to gain privileges (if they can cause my_GetTempFileName to return 0, as shown in the references).

Integer overflow in IN_MOD.DLL (aka the Module Decoder Plug-in) in Winamp before 5.57 might allow remote attackers to execute arbitrary code via an Oktalyzer file that triggers a heap-based buffer overflow.

libsndfile: overflows may lead to execution of arbitrary code

Integer overflow in libsndfile 1.0.18, as used in Winamp and other products, allows context-dependent attackers to execute arbitrary code via crafted description chunks in a CAF audio file, leading to a heap-based buffer overflow.

libsndfile AIFF file heap based buffer overflow

Heap-based buffer overflow in aiff_read_header in libsndfile 1.0.15 through 1.0.19, as used in Winamp 5.552 and possibly other media programs, allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via an AIFF file with an invalid header value.

libmikmod: arbitrary code execution via crafted Impulse Tracker or Ultratracker files

Heap-based buffer overflow in IN_MOD.DLL (aka the Module Decoder Plug-in) in Winamp before 5.57, and libmikmod 3.1.12, might allow remote attackers to execute arbitrary code via an Ultratracker file.

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.

Cross-site scripting (XSS) vulnerability in the Nullsoft ShoutcastServer 1.9.7 allows remote attackers to inject arbitrary web script or HTML via the top-level URI on the Incoming interface (port 8001/tcp), which is not properly handled in the administrator interface when viewing the log file.

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.

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.

Heap-based buffer overflow in gen_msn.dll in the gen_msn plugin 0.31 for Winamp 5.541 allows remote attackers to execute arbitrary code via a playlist (.pls) file with a long URL in the File1 field. NOTE: some of these details are obtained from third party information.

libsndfile VOC file heap based buffer overflow

Heap-based buffer overflow in voc_read_header in libsndfile 1.0.15 through 1.0.19, as used in Winamp 5.552 and possibly other media programs, allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a VOC file with an invalid header value.

The Nullsoft Modern Skins Support module (gen_ff.dll) in Nullsoft Winamp before 5.552 allows remote attackers to execute arbitrary code via a crafted MAKI file, which triggers an incorrect sign extension, an integer overflow, and a stack-based buffer overflow.

libmikmod: arbitrary code execution via crafted Impulse Tracker or Ultratracker files

Multiple heap-based buffer overflows in IN_MOD.DLL (aka the Module Decoder Plug-in) in Winamp before 5.57, and libmikmod 3.1.12, might allow remote attackers to execute arbitrary code via (1) crafted samples or (2) crafted instrument definitions in an Impulse Tracker file. NOTE: some of these details are obtained from third party information.

Multiple heap-based buffer overflows in AOL Nullsoft WinAmp before 5.31 allow user-assisted remote attackers to execute arbitrary code via a crafted (1) ultravox-max-msg header to the Ultravox protocol handler or (2) unspecified Lyrics3 tags.

LIBSNDFILE.DLL, as used by AOL Nullsoft Winamp 5.33 and possibly other products, allows remote attackers to execute arbitrary code via a crafted .MAT file that contains a value that is used as an offset, which triggers memory corruption.

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.

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

FLAC Integer overflows

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.

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.
