Microsoft Considers Earlier SHA-1 Deprecation Deadline

Tech companies continue to back away from SHA-1 like it’s an infectious disease. Microsoft, which already had plans to deprecate the crusty cryptographic algorithm by the start of 2017, decided this week to move up that deadline six months. The company said it’s considering whether it will start...

OpenEMR globals.php Authentication Bypass (CVE-2015-4453)

An authentication weakness vulnerability exists in OpenEMR, specifically in the globals.php script. The vulnerability is due to variable name collision during HTTP parameter extraction. Successful exploitation will bypass authentication and allow the attacker to gain unauthorized access to the...

Updated rsync packages fix security vulnerability

Michael Samuel discovered that rsync was vulnerable to checksum collisions. This could prevent rsync from running and syncing files successfully, which could break various applications that use and rely on rsync rhbz1197601. The patched rsync will now operate in a way that is not vulnerable to th...

Mike Mimoso and Chris Brook Discuss how the a Campaign Using the Angler Exploit Kit was Disrupted and More of the Week's News

Mike Mimoso and Chris Brook discuss the week in news–including how researchers disrupted a $30M campaign using the Angler Exploit Kit, how another researcher was forced to pull a talk from a conference, and how a practical SHA-1 collision could be months away, not years. Download:...

Practical SHA-1 Collision Attack Months Away

When Bruce Schneier made his oft-cited and mathematically sound projections about the life expectancy of the SHA-1 cryptographic algorithm, he didn’t think he was being conservative. “I thought I was being accurate given the information I had at the time,” Schneier said on Thursday. Schneier in...

Collision Attack: Widely Used SHA-1 Hash Algorithm Needs to Die Immediately

SHA-1 – one of the Internet's widely adopted cryptographic hash function – is Just about to Die. Yes, the cost and time required to break the SHA1 algorithm have fallen much faster than previously expected. According to a team of researchers, SHA-1 is so weak that it may be broken and compromised...

SSL Certificate Signed Using SHA-1 Algorithm

The remote service uses an SSL certificate chain that has been signed with SHA-1, a cryptographically weak hashing algorithm. This signature algorithm is known to be vulnerable to collision attacks. An attacker can potentially exploit this to generate another certificate with the same digital...
