Package : perl-IO-Socket-SSL
Date : May 18, 2011
Affected: 2010.1
_______________________________________________________________________
Problem Description:
A vulnerability has been found and corrected in perl-IO-Socket-SSL:
IO::Socket::SSL Perl module 1.35, when verify_mode is not VERIFY_NONE,
fails open to VERIFY_NONE instead of throwing an error when a
ca_file/ca_path cannot be verified, which allows remote attackers to
bypass intended certificate restrictions (CVE-2010-4334).
The updated packages have been patched to correct this issue.
