CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local non-authenticated attacker to execute arbitrary code.
libvdpau before 1.1.1, when used in a setuid or setgid application, allows local users to gain privileges via unspecified vectors, related to the VDPAU_DRIVER_PATH environment variable.
2) Path traversal (CVE-ID: CVE-2015-5199)
CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences in dlopen in libvdpau before 1.1.1. A remote authenticated attacker can send a specially crafted HTTP request and local users to gain privileges via the VDPAU_DRIVER environment variable.
3) Input validation error (CVE-ID: CVE-2015-5200)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote non-authenticated attacker to #BASIC_IMPACT#.
The trace functionality in libvdpau before 1.1.1, when used in a setuid or setgid application, allows local users to write to arbitrary files via unspecified vectors.
