CVE-2009-0065· NVD / CVE Program· CNA mitre

Buffer overflow in net/sctp/sm_statefuns.c in the Stream Control Transmission Protocol (sctp) implementation in the Linux kernel before 2.6.

Noroxi assessment

Priority: Plan (action score 45/100)

  • Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 16.7% (FIRST EPSS); higher than 97% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: fai-kernels (Debian:4.0) 1.17+etch.24etch2; linux-2.6 (Debian:4.0) 2.6.18.dfsg.1-24etch2; linux-2.6.24 (Debian:4.0) 2.6.24-6~etchnhalf.8etch1.

Add it to your regular patch cycle. Upgrade to fai-kernels (Debian:4.0) 1.17+etch.24etch2; linux-2.6 (Debian:4.0) 2.6.18.dfsg.1-24etch2; linux-2.6.24 (Debian:4.0) 2.6.24-6~etchnhalf.8etch1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Buffer overflow in net/sctp/sm_statefuns.c in the Stream Control Transmission Protocol (sctp) implementation in the Linux kernel before 2.6.28-git8 allows remote attackers to have an unknown impact via an FWD-TSN (aka FORWARD-TSN) chunk with a large stream ID.
