pyOpenSSL allows TLS connection bypass via unhandled callback exception in set_tlsext_servername_callback

If a user provided callback to settlsextservernamecallback raised an unhandled exception, this would result in a connection being accepted. If a user was relying on this callback for any security-sensitive behavior, this could allow bypassing it. Unhandled exceptions now result in rejecting the...

Name of the Vulnerable Software and Affected Versions Node.js version 24 Description A memory leak exists in Node.js’s OpenSSL integration when converting X.509 certificate fields to UTF-8 without freeing the allocated buffer. Calling socket.getPeerCertificatetrue causes a memory leak for each...

CVE-2018-15885

Ovation FindMe 1.4-1083-1 is intended to support transmission of network traffic from covert video recorders but does not properly disrupt binary analysis for discovering the product's capabilities or purpose. This makes it easier for adversaries to detect the covert operation. Specifically, the...

Palo Alto Networks - readSessionVarsFromFile() Session Corruption Exploit

This Metasploit module exploits a chain of vulnerabilities in Palo Alto Networks products running PAN-OS versions prior to 6.1.19, 7.0.19, 7.1.14, and 8.0.6. This chain starts by using an authentication bypass flaw to to exploit an XML injection issue, which is then abused to create an arbitrary...

Ursnif Trojan Adopts New Code Injection Technique

Hackers are testing a new variation of the Ursnif Trojan aimed at Australian bank customers that utilizes novel code injection techniques. Since the summer of 2017, IBM X-Force researchers report that Ursnif or Gozi samples have been tested in wild by a new malware developer. The samples are a...

Newly Observed Ursnif Variant Employs Malicious TLS Callback Technique to Achieve Process Injection

Introduction TLS Thread Local Storage callbacks are provided by the Windows operating system to support additional initialization and termination for per-thread data structures. As previously reported, malicious TLS callbacks, as an anti-analysis trick, have been observed for quite some time and...
