CVE-2021-27876

An issue was discovered in Veritas Backup Exec before 21.2. The communication between a client and an Agent requires successful authentication, which is typically completed over a secure TLS communication. However, due to a vulnerability in the SHA Authentication scheme, an attacker is able to ga...

CVE-2021-27878

An issue was discovered in Veritas Backup Exec before 21.2. The communication between a client and an Agent requires successful authentication, which is typically completed over a secure TLS communication. However, due to a vulnerability in the SHA Authentication scheme, an attacker is able to ga...

The vulnerability of the implementation of the HMAC-SHA-384 mechanism in the GnuTLS cryptographic library allows a perpetrator to carry out an “Lucky 13” attack and a attack that recovers the plaintext.

The vulnerability of the implementation of the HMAC-SHA-384 mechanism in the GnuTLS cryptographic library is related to errors in the implementation of the cryptographic algorithm. Exploiting this vulnerability allows a malicious actor to perform both a “Lucky 13” attack and an attack that recove...

jenkins: Non-constant time HMAC comparison

Jenkins 2.218 and earlier, LTS 2.204.1 and earlier used a non-constant time comparison function when validating an HMAC...

Mozilla: Stack buffer overflow in HKDF output

A flaw was discovered in both Firefox and Thunderbird where 4 bytes of a HMAC output could be written past the end of a buffer stored on the memory stack. This could allow an attacker to execute arbitrary code or lead to a crash. This flaw can be exploited over the network...

CVE-2019-11738

If a Content Security Policy CSP directive is defined that uses a hash-based source that takes the empty string as input, execution of any javascript: URIs will be allowed. This could allow for malicious JavaScript content to be run, bypassing CSP permissions. This vulnerability affects Firefox 6...

Input validation

If a Content Security Policy CSP directive is defined that uses a hash-based source that takes the empty string as input, execution of any javascript: URIs will be allowed. This could allow for malicious JavaScript content to be run, bypassing CSP permissions. This vulnerability affects Firefox 6...

GHSA-FGMR-VX7C-5WJ6 Timing attack on HMAC signature comparison in Apache Tapestry

The code which checks HMAC in form submissions used String.equals for comparisons, which results in a timing side channel for the comparison of the HMAC signatures. This could lead to remote code execution if an attacker is able to determine the correct signature for their payload. The comparison...

Mozilla: Content security policy bypass through hash-based sources in directives

If a Content Security Policy CSP directive is defined that uses a hash-based source that takes the empty string as input, execution of any javascript: URIs will be allowed. This could allow for malicious JavaScript content to be run, bypassing CSP permissions. This vulnerability affects Firefox 6...

Apache Mesos Information Disclosure Vulnerability

Apache Mesos is the United States Apache Apache Software Foundation of a set of support for Hadoop, ElasticSearch and Spark and other application architecture of open source cluster management software. A security vulnerability exists in the comparison of the HMAC values generated in Apache Mesos...

UBUNTU-CVE-2018-10844

It was found that the GnuTLS implementation of HMAC-SHA-256 was vulnerable to a Lucky thirteen style attack. Remote attackers could use this flaw to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of timing data using crafted packets...

openssl: Insufficient TLS session ticket HMAC length checks

An integer underflow flaw leading to a buffer over-read was found in the way OpenSSL parsed TLS session tickets. A remote attacker could use this flaw to crash a TLS server using OpenSSL if it used SHA-512 as HMAC for session tickets...

Unspecified Vulnerability in Bouncy Castle BKS-V1

Bouncy Castle is a cryptographic library for C and Java applications.BKS-V1 is one of the secret key storage format. A security vulnerability exists in Bouncy Castle BKS-V1, which stems from the fact that the length of the HMAC used in Bouncy Castle BKS-V1 files is only 16 bits. An attacker could...

Linux kernel buffer overflow vulnerability (CNVD-2017-37875)

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. A buffer overflow vulnerability exists in the HMAC implementation in versions of Linux kernel prior to 4.14.8. A local attacker could exploit this vulnerability by...
