Detail

Updated libssh packages fix security vulnerabilities:

Multiple double free flaws, buffer overflow flaws, invalid free flaws, and improper overflow checks in libssh before 0.5.3 could enable a denial of service attack against libssh clients, or possibly arbitrary code execution (CVE-2012-4559, CVE-2012-4560, CVE-2012-4561 and CVE-2012-4562).

Yong Chuan Koh discovered that libssh incorrectly handled certain negotiation requests. A remote attacker could use this to cause libssh to crash, resulting in a denial of service (CVE-2013-0176).
