perl-CryptX

NAME CryptX - Cryptographic toolkit SYNOPSIS CryptX is the distribution entry point. In normal code, load one of the concrete modules listed below. one-shot hashing use Crypt::Digest qwdigestdatahex; my $sha256 = digestdatahex'SHA256', 'hello world'; classic AES-CBC encryption with padding use...

CVE-2026-13758

A flaw was found in CryptX for Perl. The library performs a non-constant time comparison of Authenticated Encryption with Associated Data AEAD authentication tags in its streaming decryption function. This timing difference creates a tag-verification oracle, allowing a remote attacker to submit...

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...

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-2026-13758

CryptX for Perl versions before 0.088_001 are vulnerable to a timing attack in the streaming decrypt_done path. The software uses memNE (memcmp() != 0) to compare AEAD authentication tags, which short-circuits on the first differing byte. This creates a tag-verification oracle where an attacker m...
