Description Agostino Sarubbo gentoo-dev 2014-06-19 09:17:55 UTC
From ${URL} :

It was discovered [1] that there's a denial of service vulnerability in
Email::Address, a Perl module for RFC 2822 address parsing and
creation[2]. Email::Address::parse uses significant time on parsing
empty quoted string, as allowed by RFC 2822.

Suggested fix was applied upstream as [3]
contained in a new upstream version 1.905[4] which contain additional
commits to avoid slowdowns.


@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.

CVE-2014-0477 (
  The parse function in Email::Address module before 1.905 for Perl uses an
  inefficient regular expression, which allows remote attackers to cause a
  denial of service (CPU consumption) via an empty quoted string in an RFC
  2822 address.
