An update that solves 5 vulnerabilities and has three fixes
is now available.
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)
