GHSA-Q2QQ-HMJ6-3WPP hickory-proto vulnerable to CPU exhaustion during message encoding due to O(n²) name compression

During message encoding, hickory-proto's BinEncoder stores pointers to labels that are candidates for name compression in a Vec. The name compression logic then searches for matches with a linear scan. A malicious message with many records can both introduce many candidate labels, and invoke this...

SUSE CVE-2026-32936

CoreDNS is a DNS server that chains plugins. In versions prior to 1.14.3, the DNS-over-HTTPS DoH GET path accepts oversized dns= query parameter values and performs URL query parsing, base64 decoding, and DNS message unpacking before rejecting the request. Unlike the POST path, which applies a...

SUSE CVE-2026-42198

pgjdbc is an open source postgresql JDBC Driver. From version 42.2.0 to before version 42.7.11, pgjdbc is vulnerable to a client-side denial of service during SCRAM-SHA-256 authentication. A malicious server can instruct the driver to perform SCRAM authentication with a very large iteration count...
