SUSE CVE-2026-76781

A flaw was found in libxml2. A local user or an attacker providing a specially crafted XML catalog can trigger a NULL pointer dereference during XML catalog parsing. This occurs when a nextCatalog element lacks its mandatory catalog attribute, leading to the application crashing and causing a...

SUSE CVE-2026-92987

roxmltree through 0.21.1 performs quadratic-time attribute and namespace validation during XML parsing without limits on attribute count. Attackers can craft XML documents with tens of thousands of attributes on a single element to consume excessive CPU time and cause denial of service...

sslscan v2.2.3

sslscan2 sslscan version 2 has now been released. This includes a major rewrite of the backend scanning code, which means that it is no longer reliant on the version of OpenSSL for many checks. This means that it is possible to support legacy protocols SSLv2 and SSLv3, as well as supporting TLSv1...
