A double free vulnerability was discovered in Perl, possibly resulting in the execution of arbitrary code and a Denial of Service.
| Package | dev-lang/perl on all architectures |
|---|---|
| Affected versions | < 5.8.8-r5 |
| Unaffected versions | >= 5.8.8-r5 |
| Package | sys-devel/libperl on all architectures |

Perl is a stable, cross platform programming language.
Tavis Ormandy and Will Drewry of the Google Security Team have reported a double free vulnerability when processing a crafted regular expression containing UTF-8 characters.
A remote attacker could possibly exploit this vulnerability to execute arbitrary code or cause a Denial of Service.
There is no known workaround at this time.
All Perl users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-lang/perl-5.8.8-r5"
All libperl users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-devel/libperl-5.8.8-r2"
