gnutls: timing side-channel in the TLS RSA key exchange code

A timing side-channel vulnerability was found in RSA ClientKeyExchange messages in GnuTLS. This side-channel may be sufficient to recover the key encrypted in the RSA ciphertext across a network in a Bleichenbacher style attack. To achieve a successful decryption, the attacker would need to send ...

K15551553: OpenSSL vulnerability CVE-2017-3730

Security Advisory Description In OpenSSL 1.1.0 before 1.1.0d, if a malicious server supplies bad parameters for a DHE or ECDHE key exchange then this can result in the client attempting to dereference a NULL pointer leading to a client crash. This could be exploited in a Denial of Service attack...

K05909237: BouncyCastle Java crypto vulnerability CVE-2017-13098

Security Advisory Description BouncyCastle TLS prior to version 1.0.3, when configured to use the JCE Java Cryptography Extension for cryptographic functions, provides a weak Bleichenbacher oracle when any TLS cipher suite using RSA key exchange is negotiated. An attacker can recover the private...

K64009378: OpenSSL vulnerability CVE-2016-0701

Security Advisory Description The DHcheckpubkey function in crypto/dh/dhcheck.c in OpenSSL 1.0.2 before 1.0.2f does not ensure that prime numbers are appropriate for Diffie-Hellman DH key exchange, which makes it easier for remote attackers to discover a private DH exponent by making multiple...

ALPINE-CVE-2023-0361

A timing side-channel in the handling of RSA ClientKeyExchange messages was discovered in GnuTLS. This side-channel can be sufficient to recover the key encrypted in the RSA ciphertext across a network in a Bleichenbacher style attack. To achieve a successful decryption the attacker would need to...

AZL-13568 CVE-2023-0361 affecting package gnutls for versions less than 3.7.7-2

A timing side-channel in the handling of RSA ClientKeyExchange messages was discovered in GnuTLS. This side-channel can be sufficient to recover the key encrypted in the RSA ciphertext across a network in a Bleichenbacher style attack. To achieve a successful decryption the attacker would need to...

UBUNTU-CVE-2023-0361

To achieve a successful decryption the attacker would need to...

SUSE CVE-2005-3671

The Internet Key Exchange version 1 IKEv1 implementation in Openswan 2 openswan-2 before 2.4.4, and freeswan in SUSE LINUX 9.1 before 2.041.5.4-1.23, allow remote attackers to cause a denial of service via 1 a crafted packet using 3DES with an invalid key length, or 2 unspecified inputs when...

SUSE CVE-2008-1672

OpenSSL 0.9.8f and 0.9.8g allows remote attackers to cause a denial of service crash via a TLS handshake that omits the Server Key Exchange message and uses "particular cipher suites," which triggers a NULL pointer dereference...

SUSE CVE-2008-4551

strongSwan 4.2.6 and earlier allows remote attackers to cause a denial of service daemon crash via an IKESAINIT message with a large number of NULL values in a Key Exchange payload, which triggers a NULL pointer dereference for the return value of the mpzexport function in the GNU Multiprecision...

SUSE CVE-2010-2628

The IKE daemon in strongSwan 4.3.x before 4.3.7 and 4.4.x before 4.4.1 does not properly check the return values of snprintf calls, which allows remote attackers to execute arbitrary code via crafted 1 certificate or 2 identity data that triggers buffer overflows...

SUSE CVE-2010-2939

Double free vulnerability in the ssl3getkeyexchange function in the OpenSSL client ssl/s3clnt.c in OpenSSL 1.0.0a, 0.9.8, 0.9.7, and possibly other versions, when using ECDH, allows context-dependent attackers to cause a denial of service crash and possibly execute arbitrary code via a crafted...

SUSE CVE-2011-3210

The ephemeral ECDH ciphersuite functionality in OpenSSL 0.9.8 through 0.9.8r and 1.0.x before 1.0.0e does not ensure thread safety during processing of handshake messages from clients, which allows remote attackers to cause a denial of service daemon crash via out-of-order messages that violate t...

SUSE CVE-2011-3380

Openswan 2.6.29 through 2.6.35 allows remote attackers to cause a denial of service NULL pointer dereference and pluto IKE daemon crash via an ISAKMP message with an invalid KEYLENGTH attribute, which is not properly handled by the error handling function...
