wildfly-elytron: possible timing attacks via use of unsafe comparator

A flaw was found in Wildfly-elytron. Wildfly-elytron uses java.util.Arrays.equals in several places, which is unsafe and vulnerable to timing attacks. To compare values securely, use java.security.MessageDigest.isEqual instead. This flaw allows an attacker to access secure information or...

Timing Attack

python3.9 is vulnerable to Improper Access Control. The vulnerability exists due to a flaw in the way the hmac.comparedigest function in the Lib/hmac.py module compares two message digests. An attacker can exploit this vulnerability to distinguish between different message digests, which could be...

Python 竞争条件问题漏洞

Python is an open source, object-oriented programming language from the Python Foundation. The language is extensible, supports modules and packages, and supports multiple platforms. A security vulnerability exists in Python 3.9.1, which stems from the fact that the Comparedigest accumulator...

CVE-2023-40021

Oppia is an online learning platform. When comparing a received CSRF token against the expected token, Oppia uses the string equality operator ==, which is not safe against timing attacks. By repeatedly submitting invalid tokens, an attacker can brute-force the expected CSRF token character by...
