CVE-2019-18932 – Gentoo Linux Security Advisory 202007-32

https://notcve.org/view.php?id=CVE-2019-18932

21 Jan 2020 — log.c in Squid Analysis Report Generator (sarg) through 2.3.11 allows local privilege escalation. By default, it uses a fixed temporary directory /tmp/sarg. As the root user, sarg creates this directory or reuses an existing one in an insecure manner. An attacker can pre-create the directory, and place symlinks in it (after winning a /tmp/sarg/denied.int_unsort race condition). The outcome will be corrupted or newly created files in privileged file system locations. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00051.html • CWE-59: Improper Link Resolution Before File Access ('Link Following') CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
