CVE-2013-2139: Buffer overflow in srtp.c in libsrtp in srtp 1.4.5 and earlier allows remote attackers to cause a denial of service (crash) via vectors…
Noroxi assessment
Priority: Monitor (action score 11/100)
- 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: 2.9% (FIRST EPSS); higher than 87.5% of all records.
- Special conditions such as timing or configuration are required.
- Fixed version: srtp (Debian:6.0) 1.4.4~dfsg-6+deb6u1; srtp (Debian:7) 1.4.4+20100615~dfsg-2+deb7u1; libsrtp (openSUSE:Tumbleweed) 2.4.1-1.2, 1.5.4-2.1.
Low priority for now. Upgrade to srtp (Debian:6.0) 1.4.4~dfsg-6+deb6u1; srtp (Debian:7) 1.4.4+20100615~dfsg-2+deb7u1; libsrtp (openSUSE:Tumbleweed) 2.4.1-1.2, 1.5.4-2.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
Buffer overflow in srtp.c in libsrtp in srtp 1.4.5 and earlier allows remote attackers to cause a denial of service (crash) via vectors related to a length inconsistency in the crypto_policy_set_from_profile_for_rtp and srtp_protect functions.
