CVE-2021-28153

Published: Mar 11, 2021Updated: Nov 21, 2024 Sources: CVE List NVD BDU csafCWE-59
5.3CVSSMEDIUM

Description

An issue was discovered in GNOME GLib before 2.66.8. When g_file_replace() is used with G_FILE_CREATE_REPLACE_DESTINATION to replace a path that is a dangling symlink, it incorrectly also creates the target of the symlink as an empty file, which could conceivably have security relevance if the symlink is attacker-controlled. (If the path is a symlink to a file that already exists, then the contents of that file correctly remain unchanged.)
