UBUNTU-CVE-2026-14456

Issue summary: When an OpenSSL QUIC server Listener SSL object processes valid QUIC Initial packets for unknown destination connection IDs, it can allocate and queue new incoming channels without enforcing any limit. Impact summary: A remote peer that can make many Initial packets reach the serve...

CVE-2026-53794

rsync before 3.5.0 contains a logic error in --max-alloc handling that allows a sender or configuration setting --max-alloc=0 to disable allocation sanity checks entirely rather than enforcing a zero-byte cap. Attackers can exploit this flaw to cause the receiver to attempt unbounded memory...

CVE-2026-14677 PostgreSQL 32-bit pltcl and plperl undersize allocations, via integer wraparound

Integer wraparound in PostgreSQL 32-bit builds of pltcl and plperl allows an object creator to cause the server to undersize an allocation and write out-of-bounds via crafted function bodies. This may execute arbitrary code as the operating system user running the database. CVE-2026-6473 had fixe...

Elasticsearch 8.19.20, 9.4.5 Security Update (ESA-2026-76)

Allocation of Resources Without Limits or Throttling in Elasticsearch Leading to Denial of Service A flaw in Elasticsearch allows an authenticated user holding only read privileges to submit a small search request containing a crafted user-supplied input. Processing that input causes a specific...

Elasticsearch 8.19.20, 9.4.5, 9.5.1 Security Update (ESA-2026-79)

Memory Allocation with Excessive Size Value in Elasticsearch Leading to Denial of Service A flaw in Elasticsearch allows a low-privileged authenticated user to submit a single small request containing a forged opaque identifier. Elasticsearch decodes and deserializes the identifier before...

Elasticsearch 8.19.20, 9.4.5, 9.5.1 Security Update (ESA-2026-120)

Memory Allocation with Excessive Size Value in Elasticsearch Highlighting Leading to Denial of Service Elasticsearch does not enforce an upper bound on a user-supplied count accepted by a search highlighting option, and the allocation derived from that count is not accounted against any circuit...

CVE-2026-73216

A flaw was found in coturn. An authenticated client can exploit a vulnerability in the shutdownclientconnection function, which prematurely releases bandwidth accounting during the first stage of closing a mobility-enabled allocation. This allows the client to bypass user and total quotas, leadin...

Denial Of Service (DoS)

Apache ActiveMQ is vulnerable to a Memory Allocation with Excessive Size Value vulnerability. The vulnerability is due to improper handling of non-terminating STOMP header bytes, which allows an unauthenticated attacker to send an excessive amount of header data over a STOMP NIO connection, causi...
