PT-2021-21735 · Meow Hash · Meow Hash

Name of the Vulnerable Software and Affected Versions: Meow hash version 0.5/calico Description: The issue concerns a weakness in Meow hash 0.5/calico that allows an attacker to recover keys by querying whether there's a collision in the bottom bits of the hashes of two messages. This is...

GHSA-656C-6CXF-HVCV Deserialization of Untrusted Data in Flask-Caching

Flask-Cache adds easy cache support to Flask. The Flask-Caching extension through 1.10.1 for Flask relies on Pickle for serialization, which may lead to remote code execution or local privilege escalation. If an attacker gains access to cache storage e.g., filesystem, Memcached, Redis, etc., they...

Security Bulletin: A vulnerability in the GSKit component of Informix Dynamic Server (IDS) (CVE-2016-0201)

Summary A vulnerability has been addressed in the GSKit, component of Informix Dynamic Server IDS . Vulnerability Details CVEID: CVE-2016-0201 DESCRIPTION: IBM GSKit could allow a remote attacker to obtain sensitive information, caused by a MD5 collision. An attacker could exploit this...

auth collision possible

Handle gpersoon Vulnerability details Impact The auth mechanism of AccessControl.sol uses function selectors msg.sig as a unique role definition. Also the moduleCall allows the code to be extended. Suppose an attacker wants to add the innocent looking function "leftbranchblockuint32" in an new...

Insecure Random Number Generator

github.com/masterminds/goutils uses an insecure random number generator. The functions RandomAlphaNumericint and CryptoRandomAlphaNumericint does not produce secure random numbers. This allows an increased risk of brute force-style password guessing as well as a higher probability of collision...

RandomAlphaNumeric and CryptoRandomAlphaNumeric are not as random as they should be

Impact A security-sensitive bug was discovered by Open Source Developer Erik Sundell of Sundell Open Source Consulting AB. The functions RandomAlphaNumericint and CryptoRandomAlphaNumericint are not as random as they should be. Small values of int in the functions above will return a smaller subs...

CVE-2021-33026

The Flask-Caching extension through 1.10.1 for Flask relies on Pickle for serialization, which may lead to remote code execution or local privilege escalation. If an attacker gains access to cache storage e.g., filesystem, Memcached, Redis, etc., they can construct a crafted payload, poison the...

Remote code execution

DISPUTED The Flask-Caching extension through 1.10.1 for Flask relies on Pickle for serialization, which may lead to remote code execution or local privilege escalation. If an attacker gains access to cache storage e.g., filesystem, Memcached, Redis, etc., they can construct a crafted payload,...

CVE-2020-35221

The hashing algorithm implemented for NSDP password authentication on NETGEAR JGS516PE/GS116Ev2 v2.6.0.43 devices was found to be insecure, allowing attackers with access to a network capture to quickly generate multiple collisions to generate valid passwords, or infer some parts of the original...

Properties of secure hash functions

The news of NIST and their SHA-3 algorithm competition and a recent lunch and learn at Denim Group reminded me of the Cryptographic lectures I gave at UTSA. One of the hardest concepts my students had grasping was secure cryptographic hash functions, partially because of the number theory, but al...

dnsmasq: loose query name check in reply_query() makes forging replies easier for an off-path attacker

A flaw was found in dnsmasq. When getting a reply from a forwarded query, dnsmasq checks in forward.c:replyquery, which is the forwarded query that matches the reply, by only using a weak hash of the query name. Due to the weak hash CRC32 when dnsmasq is compiled without DNSSEC, SHA-1 when it is...
