This update for squid fixes the following issues :
Security issues fixed :
CVE-2018-19131: Fixed Cross-Site-Scripting vulnerability in the TLS error handling (bsc#1113668).
CVE-2018-19132: Fixed small memory leak in processing of SNMP packets (bsc#1113669).
Non-security issues fixed: Create runtime directories needed when SMP mode is enabled (bsc#1112695, bsc#1112066).
Install license correctly (bsc#1082318).
Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
