OESA-2026-4205 (CVE-2026-82560)

Vulnerability from osv_openeuler – Published: 2026-09-30 13:47 – Updated: 2026-09-30 13:47 – Source website

Summary

perl-podlators security update

Details

podlators contains Pod::Man and Pod::Text modules which convert POD input to *roff source output, suitable for man pages, or plain text. It also includes several subclasses of Pod::Text for formatted output to terminals with various capabilities. It is the source package for the Pod::Man and Pod::Text modules included with Perl.

Security Fix(es):

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)

Severity

7.5 (High)
