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)
