K15721: GnuTLS vulnerability CVE-2013-1619
Security Advisory Description The TLS implementation in GnuTLS before 2.12.23, 3.0.x before 3.0.28, and 3.1.x before 3.1.7 does not properly consider timing side-channel attacks on a noncompliant MAC check operation during the processing of malformed CBC padding, which allows remote attackers to...
K43429502: OpenSSL RSA key generation vulnerability CVE-2018-0737
Security Advisory Description The OpenSSL RSA Key generation algorithm has been shown to be vulnerable to a cache timing side channel attack. An attacker with sufficient access to mount cache timing attacks during the RSA key generation process could recover the private key. Fixed in OpenSSL...
K32562936: Intel CPU vulnerabilities CVE-2020-24511 and CVE-2020-24512
Security Advisory Description CVE-2020-24511 Improper isolation of shared resources in some IntelR Processors may allow an authenticated user to potentially enable information disclosure via local access. CVE-2020-24512 Observable timing discrepancy in some IntelR Processors may allow an...
K57214415: NAT slipstream vulnerability
Security Advisory Description This vulnerability exploits the application layer gateway ALG mechanism of network address translations NATs, routers, and firewalls through modification of internal IP extractions for a client browser connection and therefore bypasses the browser's port restrictions...
K53084033: OpenSSL vulnerability CVE-2016-2178
Security Advisory Description The dsasignsetup function in crypto/dsa/dsaossl.c in OpenSSL through 1.0.2h does not properly ensure the use of constant-time operations, which makes it easier for local users to discover a DSA private key via a timing side-channel attack. CVE-2016-2178 Impact An...
K49711130: OpenSSL and Intel processor SMT side-channel vulnerability (PortSmash) CVE-2018-5407
Security Advisory Description Simultaneous Multi-threading SMT in processors can enable local users to exploit software vulnerable to timing attacks via a side-channel timing attack on 'port contention.' CVE-2018-5407 also known as PortSmash Impact The vulnerability allows an attacker who can...
K43741620: OpenSSL vulnerabilities CVE-2018-0734 and CVE-2018-0735
Security Advisory Description CVE-2018-0734 The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in the signing algorithm to recover the private key. Fixed in OpenSSL 1.1.1a Affected 1.1.1. Fixed in OpenSSL 1.1.0j...
K15493: OpenSSH vulnerability CVE-2006-5229
Security Advisory Description OpenSSH portable 4.1 on SUSE Linux, and possibly other platforms and versions, and possibly under limited configurations, allows remote attackers to determine valid usernames via timing discrepancies in which responses take longer for valid usernames than invalid one...
K43205719: NTP input validation vulnerability CVE-2016-1550
Security Advisory Description An exploitable vulnerability exists in the message authentication functionality of libntp in ntp 4.2.8p4 and NTPSec a5fb34b9cc89b92a8fef2f459004865c93bb7f92. An attacker can send a series of crafted messages to attempt to recover the message digest key. CVE-2016-1550...
K32743437: OpenSSL vulnerability CVE-2016-7056
Security Advisory Description A timing attack flaw was found in OpenSSL 1.0.1u and before that could allow a malicious user with local access to recover ECDSA P-256 private keys. CVE-2016-7056 Impact A malicious user with local access can recover Elliptic Curve Digital Signature Algorithm ECDSA...
K15500: SSL acceleration card timing vulnerability CVE-2014-4024
Security Advisory Description SSL virtual servers in F5 BIG-IP systems 10.x before 10.2.4 HF9, 11.x before 11.2.1 HF12, 11.3.0 before HF10, 11.4.0 before HF8, 11.4.1 before HF5, 11.5.0 before HF5, and 11.5.1 before HF5, when used with third-party Secure Sockets Layer SSL accelerator cards, might...
K43357358: AMD processors vulnerability CVE-2022-23823
Security Advisory Description A potential vulnerability in some AMD processors using frequency scaling may allow an authenticated attacker to execute a timing attack to potentially enable information disclosure. CVE-2022-23823 also known as hertzbleed Impact Successful exploitation of this...
OESA-2023-1107 openssl security update
Security Fixes: The public API function BIOnewNDEF is a helper function used for streaming ASN.1 data via a BIO. It is primarily used internally to OpenSSL to support the SMIME, CMS and PKCS7 streaming capabilities, but may also be called directly by end user applications. The function receives a...
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 send a large amount of specially crafted messages to the vulnerable server. By recovering the secret from the ClientKeyExchange message the attacker would be able to decrypt the application data exchanged over that connection.
