Amazon Linux 2023 : editorconfig, editorconfig-devel, editorconfig-libs (ALAS2023-2026-1642)

high Nessus Plugin ID 315634

Language:

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2026-1642 advisory.

 editorconfig-core-c is an EditorConfig core library for use by plugins supporting EditorConfig parsing.
 Versions up to and including 0.12.10 have a stack-based buffer overflow in ec_glob() that allows an attacker to crash any application using libeditorconfig by providing a specially crafted directory structure and .editorconfig file. This is an incomplete fix for CVE-2023-0341. The pcre_str buffer was protected in 0.12.6 but the adjacent l_pattern[8194] stack buffer received no equivalent protection. On Ubuntu 24.04, FORTIFY_SOURCE converts the overflow to SIGABRT (DoS). Version 0.12.11 contains an updated fix. (CVE-2026-40489)

Tenable has extracted the preceding description block directly from the tested product 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

Run 'dnf update editorconfig --releasever 2023.11.20260511' or or 'dnf update --advisory ALAS2023-2026-1642 --releasever 2023.11.20260511' to update your system.
