    CVE-2023-46848 CVE-2024-25111
    Debian Bug : 1055252 1054537 1055250 1055251 1058721

    Several security vulnerabilities have been discovered in Squid, a full featured web proxy cache. 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 the oldstable distribution (bullseye), these problems have been fixed
    in version 4.13-10+deb11u3.

    For the stable distribution (bookworm), these problems have been fixed in version 5.7-2+deb12u1.

    We recommend that you upgrade your squid packages.
