An update that solves 5 vulnerabilities and has three fixes is now available.
Description:
This update for squid fixes the following issues:
o update to 4.15:
o CVE-2021-28652: Broken cache manager URL parsing (bsc#1185918)
o CVE-2021-28651: Memory leak in RFC 2169 response parsing (bsc#1185921)
o CVE-2021-28662: Limit HeaderLookupTable_t::lookup() to BadHdr and specific
IDs (bsc#1185919)
o CVE-2021-31806: Handle more Range requests (bsc#1185916)
o CVE-2020-25097: HTTP Request Smuggling vulnerability (bsc#1183436)
o Handle more partial responses (bsc#1185923)
o fix previous change to reinstante permissions macros, because the wrong
path has been used (bsc#1171569).
o use libexecdir instead of libdir to conform to recent changes in Factory
(bsc#1171164).
o 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).
o Change pinger and basic_pam_auth helper to use standard permissions. pinger
uses cap_net_raw=ep instead (bsc#1171569)
