Due to programming errors in Squid's HTTP request parsing, remote attackers may be able to execute a denial of service attack by sending large X-Forwarded-For header or trigger a stack buffer overflow while performing HTTP Digest authentication. Other issues facilitate request smuggling past a firewall or a denial of service against Squid's Helper process management. In regard to CVE-2023-46728: Please note that support for the Gopher protocol has simply been removed in future Squid versions. There are no plans by the upstream developers of Squid to fix this issue. We recommend to reject all Gopher URL requests instead. For Debian 10 buster, these problems have been fixed in version 4.6-1+deb10u9. We recommend that you upgrade your squid packages. For the detailed security status of squid please refer to its security tracker page at: https://security-tracker.debian.org/tracker/squid Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS - --------------------------END INCLUDED TEXT-------------------- You have received this e-mail bulletin as a result of your organisation's registration with AusCERT.
