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)

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

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.

Описание

An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to incorrect parser validation, it allows a Denial of Service attack against the Cache Manager API. This allows a trusted client to trigger memory leaks that. over time, lead to a Denial of Service via an unspecified short query string. This attack is limited to clients with Cache Manager API access privilege.

Описание

An issue was discovered in Squid 4.x before 4.15 and 5.x before 5.0.6. If a remote server sends a certain response header over HTTP or HTTPS, there is a denial of service. This header can plausibly occur in benign network traffic.
