CVE-2026-54541

Nimiq core-rs-albatross (≤ 1.5.1) contains a denial-of-service vulnerability in the TrieProof verification path used during state sync. A malicious sync peer can send a crafted TrieChunk containing two TrieProofNode values with identical keys, triggering an unconditional unwrap() on KeyNibbles::g...

CVE-2026-54541 Nimiq: Panic in TrieProof::verify via child_index unwrap on equal-length keys

Nimiq is a Rust implementation of the Nimiq Proof-of-Stake protocol based on the Albatross consensus algorithm. Prior to 1.6.0, a malicious state-sync peer can crash a syncing node by sending a crafted TrieChunk proof containing two TrieProofNode values with identical keys. TrieProof::verify call...

AZL-97665 CVE-2026-63072 affecting package openssl-fips-provider 3.1.2-2

Issue summary: OpenSSL CMS decryption sizes the key-unwrap output buffer based on querying the unwrapped key size, but the AES-WRAP-PAD unwrap primitive can write and cleanse more bytes than that query reports, causing an 8-byte out-of-bounds heap write. Impact summary: An attacker who supplies a...

CVE-2026-63072

OpenSSL CMS decryption is vulnerable to a deterministic 8-byte out-of-bounds heap write (CWE-787) in the key-unwrap path of CMS_decrypt() . The root cause is a mismatch: the output buffer is sized by querying the unwrapped key size, but the AES-WRAP-PAD primitive can write and cleanse more bytes ...

Astra Linux – Vulnerability in Heimdal, Samba

A heap-based buffer overflow vulnerability was discovered in Samba, specifically within the GSSAPI unwrapdes and unwrapdes3 routines of Heimdal. The DES and Triple-DES decryption routines in the Heimdal GSSAPI library allow for a length-limited write buffer overflow on memory allocated by malloc,...
