Summary
Moderate: squid:4 security, bug fix, and enhancement update
Details

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

The following packages have been upgraded to a later upstream version: squid (4.11). (BZ#1829467)

Security Fix(es):

  • squid: Improper input validation in request allows for proxy manipulation (CVE-2019-12520)

  • squid: Off-by-one error in addStackElement allows for heap buffer overflow and crash (CVE-2019-12521)

  • squid: Improper input validation in URI processor (CVE-2019-12523)

  • squid: Improper access restriction in url_regex may lead to security bypass (CVE-2019-12524)

  • squid: Heap overflow issue in URN processing (CVE-2019-12526)

  • squid: Information Disclosure issue in FTP Gateway (CVE-2019-12528)

  • squid: Out of bounds read in Proxy-Authorization header causes DoS (CVE-2019-12529)

  • squid: Denial of service in cachemgr.cgi (CVE-2019-12854)

  • squid: Buffer overflow in URI processor (CVE-2019-18676)

  • squid: Cross-Site Request Forgery issue in HTTP Request processing (CVE-2019-18677)

  • squid: HTTP Request Splitting issue in HTTP message processing (CVE-2019-18678)

  • squid: Information Disclosure issue in HTTP Digest Authentication (CVE-2019-18679)

  • squid: Mishandled HTML in the host parameter to cachemgr.cgi results in insecure behaviour (CVE-2019-18860)

  • squid: Improper input validation issues in HTTP Request processing (CVE-2020-8449)

  • squid: Buffer overflow in reverse-proxy configurations (CVE-2020-8450)

  • squid: DoS in TLS handshake (CVE-2020-14058)

  • squid: Request smuggling and poisoning attack against the HTTP cache (CVE-2020-15049)

  • squid: Improper input validation could result in a DoS (CVE-2020-24606)
