More information:

Fernando Russ from Groundworks Technologies reported a buffer overflow flaw in srtp, Cisco's reference implementation of the Secure Real-time Transport Protocol (SRTP), in how the crypto_policy_set_from_profile_for_rtp() function applies cryptographic profiles to an srtp_policy. A remote attacker could exploit this vulnerability to crash an application linked against libsrtp, resulting in a denial of service.

For the oldstable distribution (squeeze), this problem has been fixed in version 1.4.4~dfsg-6+deb6u1.

For the stable distribution (wheezy), this problem has been fixed in version 1.4.4+20100615~dfsg-2+deb7u1.

For the testing distribution (jessie), this problem has been fixed in version 1.4.5~20130609~dfsg-1.

For the unstable distribution (sid), this problem has been fixed in version 1.4.5~20130609~dfsg-1.

We recommend that you upgrade your srtp packages.
