Bug 882775 (CVE-2022-44789) – <dev-lang/mujs-1.3.2: code execution via UAF via crafted javascript

• Product: Gentoo Security
• Status: RESOLVED FIXED

[Description John Helmert III 2022-11-24 15:47:14 UTC]

CVE-2022-44789:

A logical issue in O_getOwnPropertyDescriptor() in Artifex MuJS 1.0.0 through 1.3.1 allows an attacker to achieve Remote Code Execution through memory corruption, via the loading of a crafted JavaScript file.

There's only one reference here and it's not upstream, but it's a
textfile of MITRE's CVE assignment response. Somehow they managed to
drop the references in the original request, one of which is a link to
the patch which is in 1.3.2:

https://github.com/ccxvii/mujs/commit/edb50ad66f7601ca9a3544a0e9045e8a8c60561f

Please bump.
