Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for squid fixes the following issues :

update to 4.15 :

CVE-2021-28652: Broken cache manager URL parsing (bsc#1185918)

CVE-2021-28651: Memory leak in RFC 2169 response parsing (bsc#1185921)

CVE-2021-28662: Limit HeaderLookupTable_t::lookup() to BadHdr and specific IDs (bsc#1185919)

CVE-2021-31806: Handle more Range requests (bsc#1185916)

CVE-2020-25097: HTTP Request Smuggling vulnerability (bsc#1183436)

Handle more partial responses (bsc#1185923)

fix previous change to reinstante permissions macros, because the wrong path has been used (bsc#1171569).

use libexecdir instead of libdir to conform to recent changes in Factory (bsc#1171164).

Reinstate permissions macros for pinger binary, because the permissions package is also responsible for setting up the cap_net_raw capability, currently a fresh squid install doesn't get a capability bit at all (bsc#1171569).

Change pinger and basic_pam_auth helper to use standard permissions.
pinger uses cap_net_raw=ep instead (bsc#1171569)

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.
