   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)

   This update was imported from the SUSE:SLE-15:Update update project.
