CVE-2026-50721

Libreswan, via the function RSAauthenticatehashsignaturerawrsa, did not correctly verify the length of the authentication hash when the SIG payload of an IKEv1 packet was encoded using PKCS 1 RSA Encryption as per RFC 2313. A remote attacker can use a variation on the Bleichenbacher attack to for...

CVE-2026-50721

CVE-2026-50721 concerns Libreswan where the function RSA_authenticate_hash_signature_raw_rsa() does not properly verify the authentication hash length when the SIG payload of an IKEv1 packet is encoded using PKCS#1 RSA Encryption per RFC 2313. This enables a remote attacker to leverage a Bleichen...

GHSA-5PMV-RX8R-WMV5 jxl-grid on 32-bit platforms has an out-of-bounds writes due to integer overflow

Summary On 32-bit platforms, decoding a crafted image may lead to out-of-bounds writes due to integer overflow in length calculation. Details & PoC The test listed below fail under miri with command cargo +nightly miri test --release -p jxl-grid Or you can use Address Sanitizer, which ignores...

GHSA-H72H-PPCX-998P Zebra has pre-handshake buffer capacity reservation based on attacker-claimed body length

Am I affected You are affected if: 1. You run zebrad up to and including v4.4.1. 2. Your node accepts inbound P2P connections network.listenaddr is set, which is the default. Summary The P2P codec's Codec::decode method calls src.reservebodylen + HEADERLEN after parsing a 24-byte protocol header,...

CVE-2026-48743

A flaw was found in Envoy, an open source edge and service proxy. This vulnerability occurs when Envoy translates an HTTP/3 request that is complete at the transport layer but still carries a nonzero Content-Length into an HTTP/1 request for an upstream server. If the upstream server responds...

CVE-2026-55952

The Erlang/OTP ssl application does not validate that the PSK identity list and binder list carried in a TLS 1.3 ClientHello pre-shared key extension have equal length before passing them to the session ticket handler. In tlshandshake13:handlepresharedkey/3, an OfferedPreSharedKeys record with a...

PYSEC-2026-712 Integer Overflow or Wraparound in OpenCV.

In opencv/modules/imgcodecs/src/utils.cpp, functions FillUniColor and FillUniGray do not check the input length, which can lead to integer overflow. If the image is from remote, may lead to remote code execution or denial of service. This affects Opencv 3.3 corresponding with OpenCV-Python 3.3.0....
