CVE-2021-42522

Memory leak via unreleased XML property values

Published Aug 25, 2022 · Updated Aug 4, 2024

A memory leak in GNOME Anjuta's bookmark loader allows attackers to increase process memory use by triggering XML property parsing. The bookmark-loading code in anjuta-bookmarks.c fails to release values returned by libxml2's xmlGetProp function after use. The public record does not identify how attackers supply the XML or expose data, and Debian classifies the issue as a GUI memory leak with no security impact.
