CVE-2026-40489 WRITEUP HIGH WRITEUP
editorconfig-core-c has incomplete fix for CVE-2023-0341
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-2023-0341 WRITEUP HIGH WRITEUP
Editorconfig < 0.12.6 - Out-of-Bounds Write
A stack buffer overflow exists in the ec_glob function of editorconfig-core-c before v0.12.6 which allowed an attacker to arbitrarily write to the stack and possibly allows remote code execution. editorconfig-core-c v0.12.6 resolved this vulnerability by bound checking all write operations over the p_pcre buffer.
