CVE-2026-69186

A flaw was found in c-ares, an asynchronous resolver library. A remote attacker can send a specially crafted DNS response that causes the aresdnsparse function to trust attacker-controlled record counts without validating if the response contains enough bytes for the claimed records. This can lea...

SUSE CVE-2026-91990

Tornado before 6.5.8 contains a memory amplification vulnerability in parsemultipartformdata that splits multipart data before validating the maxparts limit. Attackers can send crafted multipart requests with many parts to create large transient lists, exhausting server memory and causing denial ...

CVE-2026-69186

c-ares is an asynchronous resolver library. Prior to 1.34.7, aresdnsparse trusts the attacker-controlled ANCOUNT, NSCOUNT, and ARCOUNT fields before confirming that the DNS response contains enough bytes for the claimed records. Because processanswer invokes parsing before transaction ID and...

CVE-2026-84447 libheif: Derived-image indirect reference chains and tiled offsets bypass decode caching and MemoryHandle limits, causing CPU/memory amplification DoS

libheif is a HEIF and AVIF file format decoder and encoder. In 1.23.1 and earlier, crafted grid, iovl, and iden reference graphs can repeatedly decode the same base image because processedids is copied per branch and ImageItem::decodeimage has no shared operation budget. This vulnerability is fix...

CVE-2026-75029 Message parser retains every identical singleton RDATA, enabling wire-to-work amplification

In a query response, an attacker may send named multiple copies of a record that should only exist once such as an SOA record. If the RDATA is the same on all the copies, the record is appended to the in-memory RDATA set, which can cause increased memory usage of the negative cache and possibly...
