Stack-based buffer overflow in gen_jumpex.dll in Winamp before 5.64 Build 3418 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a package with a long Skin directory name. NOTE: a second buffer overflow involving a long GUI Search field to ml_local.dll was also reported. However, since it is only exploitable by the user of the application, this issue would not cross privilege boundaries unless Winamp is running under a highly restricted environment such as a kiosk.

Winamp 5.666 and earlier allows remote attackers to cause a denial of service (memory corruption and crash) via a malformed .FLV file, related to f263.w5s.

Buffer overflow in the in_mod plugin in Winamp before 5.6 allows remote attackers to have an unspecified impact via vectors related to the comment box.

Integer overflow in the in_nsv plugin in Winamp before 5.6 allows remote attackers to have an unspecified impact via vectors related to improper allocation of memory for NSV metadata, a different vulnerability than CVE-2010-2586.

The in_mp4 plugin in Winamp before 5.6 allows remote attackers to cause a denial of service (application crash) via crafted (1) metadata or (2) albumart in an invalid MP4 file.

The in_mkv plugin in Winamp before 5.6 allows remote attackers to cause a denial of service (application crash) via a Matroska Video (MKV) file containing a string with a crafted length.

Multiple integer overflows in the in_avi.dll plugin in Winamp before 5.623 allow remote attackers to execute arbitrary code via an AVI file with a crafted value for (1) the number of streams or (2) the size of the RIFF INFO chunk, leading to a heap-based buffer overflow.

Heap-based buffer overflow in the in_mod.dll plugin in Winamp before 5.623 allows remote attackers to execute arbitrary code via crafted song message data in an Impulse Tracker (IT) file. NOTE: some of these details are obtained from third party information.

The in_mod plugin in Winamp before 5.63 allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a .IT file.

The in_mod plugin in Winamp before 5.63 allows remote attackers to cause a denial of service (heap memory corruption) or possibly have unspecified other impact via a .IT file.

Multiple heap-based buffer overflows in bmp.w5s in Winamp before 5.63 build 3235 allow remote attackers to execute arbitrary code via the (1) strf chunk in BI_RGB or (2) UYVY video data in an AVI file, or (3) decompressed TechSmith Screen Capture Codec (TSCC) data in an AVI file.

Multiple heap-based buffer overflows in vp6.w5s (aka the VP6 codec) in Winamp before 5.59 Beta build 3033 might allow remote attackers to execute arbitrary code via a crafted VP6 (1) video file or (2) video stream.

Multiple integer overflows in the in_midi plugin in Winamp before 5.6 allow remote attackers to execute arbitrary code via a crafted MIDI file that triggers a buffer overflow.

Multiple integer overflows in in_nsv.dll in the in_nsv plugin in Winamp before 5.6 allow remote attackers to execute arbitrary code via a crafted Table of Contents (TOC) in a (1) NSV stream or (2) NSV file that triggers a heap-based buffer overflow.

Untrusted search path vulnerability in Nullsoft Winamp 5.581, and probably other versions, allows local users, and possibly remote attackers, to execute arbitrary code and conduct DLL hijacking attacks via a Trojan horse wnaspi32.dll that is located in the same folder as a .669, .aac, .aiff, .amf, .au, .avr, .b4s, .caf or .cda file.

Nullsoft Scriptable Install System (NSIS) before 3.09 mishandles access control for an uninstaller directory.

Nullsoft Scriptable Install System (NSIS) before 2.49 has unsafe implicit linking against Version.dll. In other words, there is no protection mechanism in which a wrapper function resolves the dependency at an appropriate time during runtime.

Nullsoft Scriptable Install System (NSIS) before 2.49 uses temporary folder locations that allow unprivileged local users to overwrite files. This allows a local attack in which either a plugin or the uninstaller can be replaced by a Trojan horse program.
