CVE-2009-3995: 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

Noroxi assessment

Priority: Monitor (action score 39/100)

  • 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: 6.7% (FIRST EPSS); higher than 93.9% of all records.
  • Fixed version: libmikmod (Debian:12) 3.1.11-6.2; libmikmod (Debian:5.0) 3.1.11-6+lenny1, 3.1.11-6.0.1+lenny1; mikmod (Red Hat:enterprise_linux:3::as) 0:3.1.6-23.el3.

Low priority for now. Upgrade to libmikmod (Debian:12) 3.1.11-6.2; libmikmod (Debian:5.0) 3.1.11-6+lenny1, 3.1.11-6.0.1+lenny1; mikmod (Red Hat:enterprise_linux:3::as) 0:3.1.6-23.el3 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

EPSS, last 120 days

FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No commit or PR link among the references.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
