The vulnerability of the check_session_buf_not_used() function in the tls-crypt-v2 software of OpenVPN allows a malicious individual to gain unauthorized access to protected information, cause service failures, or execute arbitrary code.

The vulnerability of the checksessionbufnotused function in the tls-crypt-v2 software of OpenVPN allows for the use of memory after it is freed. Exploiting this vulnerability could enable a remote attacker to cause a service failure or execute arbitrary code...

CVE-2026-14570

Crypt::DSA versions before 1.22 for Perl draw the DSA signing nonce and private key from a biased random generator, leading to private-key recovery. "Crypt::DSA::Util::makerandom forces the high bit of every value it returns to obtain an exactly N-bit integer for prime search. The signing nonce a...

CVE-2026-14570

CVE-2026-14570 affects Crypt::DSA for Perl up to version 1.21, where Crypt::DSA::Util::makerandom biases the top bit to produce N-bit integers. This causes the DSA signing nonce and the private key to be drawn from a non-uniform distribution. Attackers who observe a modest number of signatures un...

[SECURITY] Fedora 44 Update: perl-Crypt-PBKDF2-0.261630-1.fc44

PBKDF2 is a secure password hashing algorithm that uses the techniques of "key strengthening" to make the complexity of a brute-force attack arbitrarily hig h. PBKDF2 uses any other cryptographic hash or cipher by convention, usually HMAC-SHA2, but Crypt::PBKDF2 is fully pluggable, and allows for...
