FreeBSD ip6_setpktopt Use-After-Free Privilege Escalation Exploit

This Metasploit module exploits a race and use-after-free vulnerability in the FreeBSD kernel IPv6 socket handling. A missing synchronization lock in the IPV62292PKTOPTIONS option handling in setsockopt permits racing ip6setpktopt access to a freed ip6pktopts struct. This exploit overwrites the...

freeradius: eap-pwd: Information leak due to aborting when needing more than 10 iterations

An information leak was discovered in the implementation of EAP-pwd in freeradius. An attacker could initiate several EAP-pwd handshakes to leak information, which can then be used to recover the user's WiFi password by performing dictionary and brute-force attacks...

The vulnerability of the RsaKeyPairGenerator::getNumberOfIterations() method in the Bouncy Castle library allows a hacker to gain unauthorized access to protected data.

The vulnerability of the RsaKeyPairGenerator::getNumberOfIterations method in the Bouncy Castle library is related to deficiencies in the use of cryptographic keys. Exploiting this vulnerability could allow an attacker to gain unauthorized access to protected data using network protocols such as...

OpenJPEG 'opj_t1_encode_cblks' function too many iterations vulnerability

OpenJPEG is a C-based open source JPEG 2000 codec . A security vulnerability exists in the 'opjt1encodecblks' function in the openjp2/t1.c file in OpenJPEG version 2.3.0. A remote attacker can exploit this vulnerability to cause a denial of service with a specially crafted bmp file...

python-django: User enumeration through timing difference on password hasher work factor upgrade

A timing attack flaw was found in the way Django's PBKDF2PasswordHasher performed password hashing. Passwords hashed with an older version of PBKDF2PasswordHasher used less hashing iterations, and thus allowed an attacker to enumerate existing users based on the time differences in the login...

dns-nsec3-enum NSE Script

Tries to enumerate domain names from the DNS server that supports DNSSEC NSEC3 records. The script queries for nonexistant domains until it exhausts all domain ranges keeping track of hashes. At the end, all hashes are printed along with salt and number of iterations used. This technique is known...
