Threats Tagged 'cve-2026-48962'

This advisory addresses two security vulnerabilities in the Perl 5.32 packages used in Red Hat Enterprise Linux 8. The first vulnerability (CVE-2026-42496) involves a path traversal issue in perl-archive-tar that allows arbitrary file access via crafted symlinks. The second vulnerability (CVE-2026-48962) affects perl-IO-Compress and allows arbitrary code execution through an attacker-controlled output glob. Red Hat has released an important security update to fix these issues in the affected Perl packages.

IO::Compress versions before 2.220 for Perl can execute arbitrary code in File::GlobMapper via an attacker-controlled output glob. _parseOutputGlob() wraps the caller-supplied output glob string in double quotes and stores it in the parser state; _getFiles() then runs the stored expression through eval STRING. A literal double quote in the output glob closes the dquote wrapper, and the characters that follow are evaluated as Perl. Arbitrary Perl in the output glob executes at the calling process's privilege.

Perl is a high-level programming language that is commonly used for system administration utilities and web programming. Security Fix(es): * perl: Perl threads have a working directory race condition where file operations may target unintended paths (CVE-2025-40909) 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.
