CVE-2026-43970

A flaw was found in cowlib. This vulnerability, categorized as Improper Handling of Highly Compressed Data Data Amplification, allows an unauthenticated remote attacker to cause a denial of service DoS. By sending a specially crafted SPDY frame, the cowspdy:inflate/2 function in cowlib passes...

netty: Netty: Denial of Service via HTTP/2 CONTINUATION frame flood

A flaw was found in Netty. A remote user can trigger a Denial of Service DoS against a Netty HTTP/2 server by sending a flood of CONTINUATION frames. The server's lack of a limit on these frames, coupled with a bypass of size-based mitigations using zero-byte frames, allows an attacker to consume...

CVE-2026-42786

A flaw was found in bandit. A remote, unauthenticated attacker can exploit an Allocation of Resources Without Limits or Throttling vulnerability in the fragment reassembly path of the WebSocket connection handling. This allows the attacker to send an unbounded number of continuation frames, leadi...

CVE-2026-42788

A flaw was found in bandit. An unauthenticated remote attacker can exploit a vulnerability in the HTTP/2 frame deserialization process by sending oversized HTTP/2 frames. This allows the attacker to force the server to buffer excessive amounts of memory, leading to memory exhaustion and a denial ...

RUSTSEC-2026-0154 Unbounded 32-bit allocation

Both the SSH agent server and client accepted peer-controlled frame lengths without enforcing a maximum frame size. This could cause large memory allocations while parsing a maliciously crafted agent frame. A malicious peer could advertise an oversized frame length, causing the client or server t...

RUSTSEC-2026-0153 Unchecked `CryptoVec` allocation and growth handling

CryptoVec used unchecked capacity growth, unchecked length arithmetic, and unsafe allocation and locking paths. In affected russh releases, attacker-controlled input could reach these code paths through buffer resizing operations. Two affected reachability paths were identified: Current russh...
