Test ID:1.3.6.1.4.1.25623.1.0.703182
Category:Debian Local Security Checks
Title:Debian: Security Advisory (DSA-3182-1)
Summary:The remote host is missing an update for the Debian 'libssh2' package(s) announced via the DSA-3182-1 advisory.
Description:Summary:
The remote host is missing an update for the Debian 'libssh2' package(s) announced via the DSA-3182-1 advisory.

Vulnerability Insight:
Mariusz Ziulek reported that libssh2, a SSH2 client-side library, was reading and using the SSH_MSG_KEXINIT packet without doing sufficient range checks when negotiating a new SSH session with a remote server. A malicious attacker could man in the middle a real server and cause a client using the libssh2 library to crash (denial of service) or otherwise read and use unintended memory areas in this process.

For the stable distribution (wheezy), this problem has been fixed in version 1.4.2-1.1+deb7u1.

We recommend that you upgrade your libssh2 packages.

Affected Software/OS:
'libssh2' package(s) on Debian 7.

Solution:
Please install the updated package(s).

CVSS Score:
6.8
