CVE-2012-4562  (opens in a new tab)
CWE-189  (opens in a new tab)

How to fix?

Upgrade libssh to version 0.5.3 or higher.

Overview

Affected versions of this package are vulnerable to Denial of Service (DoS). Multiple integer overflows in libssh before 0.5.3 allow remote attackers to cause a denial of service (infinite loop or crash) and possibly execute arbitrary code via unspecified vectors, which triggers a buffer overflow, infinite loop, or possibly some other unspecified vulnerabilities.
