Description Jan Lieskovsky 2013-06-03 11:02:40 UTC

A security flaw was found in the way Subversion, a concurrent version control system, sanitized content of arguments passed to 'check-mime-type.pl' and 'svn-keyword-check.pl' hook scripts. A remote, authenticated attacker could provide a specially-crafted filename that if inspected by some of the aforementioned two scripts, would lead to arbitrary code execution with the privileges of the user running Subversion client.

Comment 4 Huzaifa S. Sidhpurwala 2013-06-04 07:12:54 UTC

This security flaw exists in the 'check-mime-type.pl' and 'svn-keyword-check.pl' contrib scripts of subversion. The version of subversion shipped with Red Hat Enterprise Linux 5 and 6 does not ship these scripts.

Statement:

Not Vulnerable. This issue does not affect the version of subversion as shipped with Red Hat Enterprise Linux 5 and 6.

Comment 6 Huzaifa S. Sidhpurwala 2013-06-04 07:19:46 UTC

This issue does not affect the version of subversion as shipped with Fedora 17 and Fedora 18.
