Astra Linux – Vulnerability in gnutls28

A timing side-channel vulnerability in the handling of RSA ClientKeyExchange messages was discovered in GnuTLS. This side-channel can be used to recover the key encrypted in the RSA ciphertext across a network, in a Bleichenbacher-style attack. To successfully decrypt the data, the attacker would...

Astra Linux – Vulnerability in libssh

A flaw was discovered in libssh’s handling of key exchange KEX processes when a client repeatedly sends incorrect KEX guesses. The library fails to free memory during these rekey operations, which can gradually exhaust system memory. This issue can lead to crashes on the client side, especially...

Astra Linux – Vulnerability in wpa

In Hostapd 2.10 and earlier, the PKEX code remains active even after a successful PKEX association. An attacker who has successfully bootstrapped public keys with another entity using PKEX in the past will be able to subvert future bootstrapping attempts by passively observing the public keys. By...
