Fedora 43 : perl-Spreadsheet-XLSX (2026-0942a5b9ea)

high Nessus Plugin ID 378077

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 43 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2026-0942a5b9ea advisory.

 # Spreadsheet::XLSX 0.20
 - Security: limit ZIP entry counts and uncompressed sizes; read members incrementally and reject inconsistent size metadata.
 - Security: validate number format IDs and escape regex lookups to prevent regex injection from crafted styles.
 - Security: reject out-of-range date values to prevent excessive CPU usage.
 - Security: validate cell references against XLSX worksheet limits before indexing cell arrays, preventing excessive allocation from invalid rows.
 - Improve Readme.

 # Spreadsheet::XLSX 0.19
 - Security: replace string eval of number-format conditions with strict numeric comparisons; invalid conditions use the fallback format section. Prevents arbitrary Perl code execution when parsing crafted XLSX files.
 - Add regression tests for numeric conditions and malicious XLSX formats.

Tenable has extracted the preceding description block directly from the Fedora security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected perl-Spreadsheet-XLSX package.
