Red Hat Security Advisory: perl-IO-Compress security update
This distribution provides a Perl interface to allow reading and writing of compressed data created with the zlib and bzip2 libraries. IO-Compress supports reading and writing of bzip2, RFC 1950, RFC 1951, RFC 1952 (i.e. gzip) and zip files/buffers. The following modules used to be distributed separately, but are now included with the IO-Compress distribution: * Compress-Zlib * IO-Compress-Zlib * IO-Compress-Bzip2 * IO-Compress-Base Security Fix(es): * perl-IO-Compress: perl-IO-Compress: Arbitrary code execution via attacker-controlled output glob (CVE-2026-48962) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
AI Analysis
Technical Summary
The perl-IO-Compress distribution, which includes modules for handling compressed data formats such as bzip2, gzip, and zip, contains a vulnerability (CVE-2026-48962) that permits arbitrary code execution through an attacker-controlled output glob. This vulnerability affects Red Hat Enterprise Linux 9.2 across various architectures including x86_64, ppc64le, aarch64, and s390x. Red Hat Product Security has rated this update as Important and released patched versions of perl-IO-Compress to remediate the issue. The advisory references Red Hat's errata RHSA-2026:29210 and provides packages for update.
Potential Impact
Successful exploitation of this vulnerability could allow an attacker to execute arbitrary code on affected systems, potentially leading to full system compromise. The vulnerability arises from unsafe handling of output globs controlled by an attacker within the perl-IO-Compress module. This poses a high security risk to systems running vulnerable versions of Red Hat Enterprise Linux 9.2.
Mitigation Recommendations
Red Hat has released an official security update for perl-IO-Compress in Red Hat Enterprise Linux 9.2 to address CVE-2026-48962. Users should apply this update promptly by following the instructions in the Red Hat advisory RHSA-2026:29210 (https://access.redhat.com/articles/11258). No additional mitigation steps are indicated beyond applying the vendor-provided patch.
