Memory leak in RFC 2169 response parsing (bsc#1185921)\n- CVE-2021-28662: Limit HeaderLookupTable_t::lookup() to BadHdr and specific IDs (bsc#1185919)\n- CVE-2021-31806: Handle more Range requests (bsc#1185916)\n- CVE-2020-25097: HTTP Request Smuggling vulnerability (bsc#1183436)\n- Handle more partial responses (bsc#1185923)\n- fix previous change to reinstante permissions macros, because the wrong path has been used (bsc#1171569).\n- use libexecdir instead of libdir to conform to recent changes in Factory (bsc#1171164).\n- Reinstate permissions macros for pinger binary, because the permissions\n  package is also responsible for setting up the cap_net_raw capability,\n  currently a fresh squid install doesn't get a capability bit at all (bsc#1171569).\n- Change pinger and basic_pam_auth helper to use standard permissions. pinger uses cap_net_raw=ep instead (bsc#1171569)\n\nThis update was imported from the SUSE:SLE-15:Update update project.","title":"Description of the
