Mandriva Linux Security Advisory : libssh (MDVSA-2013:045)

This script is Copyright (C) 2013-2014 Tenable Network Security, Inc.


Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

Description :

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).

Solution :

Update the affected lib64ssh-devel and / or lib64ssh4 packages.

Risk factor :

High / CVSS Base Score : 7.5
(CVSS2#AV:N/AC:L/Au:N/C:P/I:P/A:P)
CVSS Temporal Score : 6.5
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : false
