CVE-2014-1928

Advisory

Python-gnupg 0.3.6 includes a fix for CVE-2014-1928: 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.
