An update of the squid package has been released.

The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2024:0455-1 advisory.

  - Squid is a caching proxy for the Web. Due to an Uncontrolled Recursion bug in versions 2.6 through     2.7.STABLE9, versions 3.1 through 5.9, and versions 6.0.1 through 6.5, Squid may be vulnerable to a Denial     of Service attack against HTTP Request parsing. This problem allows a remote client to perform Denial of     Service attack by sending a large X-Forwarded-For header when the follow_x_forwarded_for feature is     configured. This bug is fixed by Squid version 6.6. In addition, patches addressing this problem for the     stable releases can be found in Squid's patch archives. (CVE-2023-50269)

  - Squid is a caching proxy for the Web. Due to an expired pointer reference bug, Squid prior to version 6.6     is vulnerable to a Denial of Service attack against Cache Manager error responses. This problem allows a     trusted client to perform Denial of Service when generating error pages for Client Manager reports. Squid     older than 5.0.5 have not been tested and should be assumed to be vulnerable. All Squid-5.x up to and     including 5.9 are vulnerable. All Squid-6.x up to and including 6.5 are vulnerable. This bug is fixed by     Squid version 6.6. In addition, patches addressing this problem for the stable releases can be found in     Squid's patch archives. As a workaround, prevent access to Cache Manager using Squid's main access     control: `http_access deny manager`. (CVE-2024-23638)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Redhat Enterprise Linux 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2024:4861 advisory.

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

    Security Fix(es):

    * squid: vulnerable to a Denial of Service attack against Cache Manager error responses (CVE-2024-23638)

    * squid: Out-of-bounds write error may lead to Denial of Service (CVE-2024-37894)

    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.
