Authentication flaw

Radware devices use the same value for the first two GCM nonces, which allows remote attackers to obtain the authentication key and spoof data via a "forbidden attack," a similar issue to CVE-2016-0270. NOTE: this issue may be due to the use of a third-party Cavium product...

CVE-2017-5933

Citrix NetScaler ADC and NetScaler Gateway 10.5 before Build 65.11, 11.0 before Build 69.12/69.123, and 11.1 before Build 51.21 randomly generates GCM nonces, which makes it marginally easier for remote attackers to obtain the GCM authentication key and spoof data by leveraging a reused nonce in ...

CVE-2016-10213

A10 AX1030 and possibly other devices with software before 2.7.2-P8 uses random GCM nonce generations, which makes it easier for remote attackers to obtain the authentication key and spoof data by leveraging a reused nonce in a session and a "forbidden attack," a similar issue to CVE-2016-0270...

CVE-2016-0270

IBM Domino 9.0.1 Fix Pack 3 Interim Fix 2 through 9.0.1 Fix Pack 5 Interim Fix 1, when using TLS and AES GCM, uses random nonce generation, which makes it easier for remote attackers to obtain the authentication key and spoof data by leveraging the reuse of a nonce in a session and a "forbidden...

CVE-2016-10213

CVE-2016-10213 affects A10 AX1030 and possibly other devices running software before 2.7.2-P8. The vulnerability arises from random GCM nonce generation, enabling remote attackers to obtain the authentication key and spoof data by reusing a nonce in a session, described as a “forbidden attack” si...

CVE-2016-10212

CVE-2016-10212 describes a GCM nonce reuse issue in Radware devices (note: may involve a third-party Cavium product) that allows remote attackers to obtain the authentication key and spoof data via a “forbidden attack.” Root cause: reuse of the initial nonces in GCM. Affected: Radware devices. Ex...

CVE-2016-0270

IBM Domino 9.0.1 Fix Pack 3 Interim Fix 2 through 9.0.1 Fix Pack 5 Interim Fix 1 is affected when using TLS with AES-GCM; the vulnerability arises from nonce generation randomness leading to nonce reuse, enabling remote attackers to obtain the authentication key and spoof data (CVE-2016-0270). Th...

CVE-2017-5933 - Vulnerability in Citrix NetScaler Application Delivery Controller and NetScaler Gateway GCM nonce generation

Description of Problem A flaw in NetScaler ADC and Gateway causes GCM nonces to be randomly generated, making it marginally easier for remote attackers to obtain the GCM authentication key and spoof data within a session. The following vulnerability has been addressed: CVE-2017-5933: Vulnerabilit...

CVE-2016-2427

The AES-GCM specification in RFC 5084, as used in Android 5.x and 6.x, recommends 12 octets for the aes-ICVlen parameter field, which might make it easier for attackers to defeat a cryptographic protection mechanism and discover an authentication key via a crafted application, aka internal bug...

kernel: net: slab corruption from use after free on INIT collisions

A use-after-free flaw was found in the way the Linux kernel's SCTP implementation handled authentication key reference counting during INIT collisions. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system...

ntp: automatic generation of weak default key in config_auth()

It was found that ntpd automatically generated weak keys for its internal use if no ntpdc request authentication key was specified in the ntp.conf configuration file. A remote attacker able to match the configured IP restrictions could guess the generated key, and possibly use it to send ntpdc...

MGASA-2014-0541 Updated ntp packages fix security vulnerabilities

Updated ntp packages fix security vulnerabilities: If no authentication key is defined in the ntp.conf file, a cryptographically-weak default key is generated CVE-2014-9293. ntp-keygen before 4.2.7p230 uses a non-cryptographic random number generator with a weak seed to generate symmetric keys...
