Amazon Linux 2023 Security Advisory: ALAS2023-2026-3399
Advisory Released Date: 2026-11-09
Advisory Updated Date: 2026-11-09
Severity:
Medium
Issue Overview:
Pod::Text versions before 6.1.1 for Perl allow CPU and memory exhaustion formatting a POD document whose =over nesting drives the margin to the output width.
Each =over adds its indent to the margin, which wrap() subtracts from the output width to get the space available for text. When that space reaches zero, the line-splitting substitution matches the empty string, and the loop consumes no input while appending the margin padding on every pass.
Formatting an attacker-supplied POD document never returns, and the output grows until memory is exhausted. (CVE-2026-82560)
Affected Packages:
perl-podlators
Issue Correction:
