This update for squid fixes the following issues :
squid was updated to version 4.12
Security issue fixed :
CVE-2020-14059: Fixed an issue where a client could potentially deny the service of a server during TLS Handshake (bsc#1173304).
Other issues addressed :
Reverted to slow search for new SMP shm pages due to a regression
Fixed an issue where negative responses were never cached
Fixed stall if transaction was overwriting a recently active cache entry
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.
