Security update for squid
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)

Описание
An issue was discovered in Squid through 4.13 and 5.x through 5.0.4. Due to improper input validation, it allows a trusted client to perform HTTP Request Smuggling and access services otherwise forbidden by the security controls. This occurs for certain uri_whitespace configuration settings.

Описание
An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to a buffer-management bug, it allows a denial of service. When resolving a request with the urn: scheme, the parser leaks a small amount of memory. However, there is an unspecified attack methodology that can easily trigger a large amount of memory consumption.

This attack is limited to clients with Cache Manager API access privilege.
