Summary
Important: squid:4 security update
Details

Squid is a high-performance proxy caching server for web clients, supporting FTP, Gopher, and HTTP data objects.

Security Fix(es):

  • squid: improper check for new member in ESIExpression::Evaluate allows for stack buffer overflow (CVE-2019-12519)

  • squid: improper access restriction upon Digest Authentication nonce replay could lead to remote code execution (CVE-2020-11945)

  • squid: parsing of header Proxy-Authentication leads to memory corruption (CVE-2019-12525)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
