Package : dropbear Vulnerability : use after free Problem type : remote Debian-specific: no CVE ID : CVE-2012-0920
Danny Fullerton discovered a use-after-free in the Dropbear SSH daemon, resulting in potential execution of arbitrary code. Exploitation is limited to users, who have been authenticated through public key authentication and for which command restrictions are in place.
For the stable distribution (squeeze), this problem has been fixed in version 0.52-5+squeeze1.
For the testing distribution (wheezy), this problem has been fixed in version 2012.55-1.
For the unstable distribution (sid), this problem has been fixed in version 2012.55-1.
We recommend that you upgrade your dropbear packages.
