  - 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&#x27 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)");
