** CVE added: https://cve.mitre.org/cgi-bin/cvename.cgi?name=2017-12425
** Changed in: varnish (Ubuntu) Status: Incomplete => Opinion ** Changed in: varnish (Ubuntu) Status: Opinion => In Progress ** Description changed: https://varnish-cache.org/security/VSV00001.html - CVE-<to be assigned, we couldn’t get one under embargo> + CVE-2017-12425 Date: 2017-08-02 A wrong if statement in the varnishd source code means that particular invalid requests from the client can trigger an assert. This causes the varnishd worker process to abort and restart, loosing the cached contents in the process. An attacker can therefore crash the varnishd worker process on demand and effectively keep it from serving content - a Denial-of-Service attack. Mitigation is possible from VCL or by updating to a fixed version of Varnish Cache. Versions affected - 4.0.1 to 4.0.4 - 4.1.0 to 4.1.7 - 5.0.0 - 5.1.0 to 5.1.2 + 4.0.1 to 4.0.4 + 4.1.0 to 4.1.7 + 5.0.0 + 5.1.0 to 5.1.2 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1708354 Title: [CVE] Correctly handle bogusly large chunk sizes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/varnish/+bug/1708354/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
