Local privilege escalation in Nullsoft Scriptable Install System (NSIS) 3.06.1 before 3.12 arises because an installer running as SYSTEM can fall back to the world-writable Low Integrity temp directory (c:\Windows\Temp\Low) when temp-file creation fails, letting a local low-privileged attacker plant content that the SYSTEM process trusts and thereby gain SYSTEM privileges. Exploitation requires an elevated NSIS installer to execute (UI:R) and hinges on forcing my_GetTempFileName to return 0, per the referenced bug #1326. There is no public exploit identified at time of analysis and EPSS is negligible (0.01%), consistent with SSVC exploitation status 'none'.
Nullsoft Scriptable Install System (NSIS) before 3.09 mishandles access control for an uninstaller directory. Rated medium severity (CVSS 5.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity.
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. Rated medium severity (CVSS 4.3), this vulnerability is remotely exploitable. Public exploit code available and EPSS exploitation probability 17.0%.
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. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and EPSS exploitation probability 40.7%.
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. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
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. Rated medium severity (CVSS 6.8), this vulnerability is remotely exploitable. This Buffer Overflow vulnerability could allow attackers to corrupt memory to execute arbitrary code or crash the application.
