Vulnerability from csaf_redhat - Published: 2008-06-17 16:08 - Updated: 2025-11-21 17:33Summary
Red Hat Security Advisory: perl security update
Severity
Important
Notes
Topic: Updated perl packages that fix a security issue are now available for Red
Hat Application Stack v1.
This update has been rated as having important security impact by the Red
Hat Security Response Team.
Details: Perl is a high-level programming language commonly used for system
administration utilities and Web programming.
A flaw was found in Perl's regular expression engine. A specially crafted
regular expression with Unicode characters could trigger a buffer overflow,
causing Perl to crash, or possibly execute arbitrary code with the
privileges of the user running Perl. (CVE-2008-1927)
Users of perl are advised to upgrade to these updated packages, which
contain a backported patch to resolve this issue.

Double free vulnerability in Perl 5.8.8 allows context-dependent attackers to cause a denial of service (memory corruption and crash) via a crafted regular expression containing UTF8 characters. NOTE: this issue might only be present on certain operating systems.
