CVE-2019-18932

https://notcve.org/view.php?id=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. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00051.html http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00063.html http://www.openwall.com/lists/oss-security/2020/01/20/6 http://www.openwall.com/lists/oss-security/2020/01/27/1 https://bugzilla.suse.com/show_bug.cgi?id=1150554 https://seclists.org/oss-sec/2020/q1/23 https://security.gentoo.org/glsa/202007-32 https://sourceforge.net/projects/sarg • CWE-59: Improper Link Resolution Before File Access ('Link Following') CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
