    Package        : varnish     Version        : 6.5.1-1+deb11u5     CVE ID         : CVE-2025-47905

    A client-side desync vulnerability can be triggered in Varnish, a     high-performance web accelerator. An attacker can abuse a flaw in Varnishs     handling of chunked transfer encoding which allows certain malformed HTTP/1     requests to exploit improper framing of the message body to smuggle additional     requests. Specifically, Varnish incorrectly permits CRLF to be skipped to     delimit chunk boundaries.

    For Debian 11 bullseye, this problem has been fixed in version     6.5.1-1+deb11u5.

    We recommend that you upgrade your varnish packages.

    For the detailed security status of varnish please refer to     its security tracker page at:
