OSEC-2026-12 AEAD `decrypt_into` functions writes plaintext before checking the tag

On the generic GCM path, AES.GCM.authenticatedecryptinto as well as Chacha20.authenticatedecryptinto and AES.CCM16.authenticatedecryptinto writes the decrypted plaintext into the caller's destination buffer and only then compares the tag. On a forged tag the function returns false, but the...

SUSE-SU-2026:22948-1 Security update for libssh

This update for libssh fixes the following issues: - CVE-2026-15370: stack buffer overflow in SFTP server longname construction bsc1272162. - CVE-2026-59843: denial of service via zero advertised channel packet size bsc1272164. - CVE-2026-59844: denial of service via oversized SFTP read length...

EUVD-2026-46318

When verifying a mac with a ChunkedMacVerification object, Tink compares the resulting tag with non constant time comparison. This potentially allows an attacker to use timinig information as a side channel in order to get information how many bytes of a given tag match the correct tag. This in...

CVE-2026-59847

A flaw was found in libssh. Incorrect AES-GCM finalization checks in builds using the OpenSSL backend can effectively remove integrity protection, allowing an in-path attacker to modify plaintext on the wire without detection...

Linux Distros Unpatched Vulnerability : CVE-2026-13758

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - CryptX versions before 0.088001 for Perl compare AEAD authentication tags in non-constant time in the streaming decryptdone path. The decryptdone$tag form...

UBUNTU-CVE-2026-13758

CryptX versions before 0.088001 for Perl compare AEAD authentication tags in non-constant time in the streaming decryptdone path. The decryptdone$tag form compares it against the computed tag with memNE memcmp != 0, which short-circuits on the first differing byte, so its run time depends on the...

CVE-2026-6331

HMAC zero-length tag forgery in EVPDigestVerifyFinal, where a zero-length tag could be accepted as valid during HMAC verification. In the OpenSSL-compatibility HMAC verify path the supplied signature length was only checked as not exceeding the MAC length, so a zero-length or otherwise truncated...

CVE-2026-6986

A flaw was found in Cesanta Mongoose. A remote attacker could exploit a vulnerability in the GCM Authentication Tag Handler, specifically within the mgaesgcmdecrypt function. This flaw allows for improper verification of cryptographic signatures, which could lead to a bypass of integrity checks...

gitverify has improper tag signature verification

gitverify is still a prototype. Impact The bug is related to requireSignedTags which is on by default: an unsigned annotated tag would pass the verification. The commit pointed to by the tag would still have to be signed by a maintainer or a contributor. Patches Since the initial commit, fixed in...
