CVE-2019-18932

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.
