HighCVSS 7.5 · v2.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 31/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 4.3% (FIRST EPSS); higher than 91.3% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: vlc (Debian:12) 1.1.3-1.

Low priority for now. Upgrade to vlc (Debian:12) 1.1.3-1 or later.

Multiple stack-based buffer overflows in VideoLAN VLC media player before 1.0.2 allow remote attackers to execute arbitrary code via (1) a crafted ASF file, related to the ASF_ObjectDumpDebug function in modules/demux/asf/libasf.c; (2) a crafted AVI file, related to the AVI_ChunkDumpDebug_level function in modules/demux/avi/libavi.c; or (3) a crafted MP4 file, related to the __MP4_BoxDumpStructure function in modules/demux/mp4/libmp4.c.
