Detailsinfo

A vulnerability has been found in python-gnupg 0.3.5 (Programming Language Software) and classified as problematic. This vulnerability affects the function shell_quote. The manipulation with an unknown input leads to a input validation vulnerability. The CWE definition for the vulnerability is CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

The shell_quote function in python-gnupg 0.3.5 does not properly escape characters, which allows context-dependent attackers to execute arbitrary code via shell metacharacters in unspecified vectors, as demonstrated using "\" (backslash) characters to form multi-command sequences, a different vulnerability than CVE-2014-1927. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-7323.

The weakness was released 10/25/2014 by Matthew Daley as 98 (Website). The advisory is available at code.google.com. This vulnerability was named CVE-2014-1928 since 02/09/2014. The exploitation appears to be easy. Local access is required to approach this attack. No form of authentication is required for a successful exploitation. Technical details are known, but there is no available exploit.

The vulnerability scanner Nessus provides a plugin with the ID 74313 (Debian DSA-2946-1 : python-gnupg - security update), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks.
