TLS 1.2 Transcipt Collision attacks against MD5 in key exchange protocol (SLOTH)

A flaw was found in the way TLS 1.2 could use the MD5 hash function for signing ServerKeyExchange and Client Authentication packets during a TLS handshake. A man-in-the-middle attacker able to force a TLS connection to use the MD5 hash function could use this flaw to conduct collision attacks to...

Mozilla Warns of SHA-1 Deprecation Side Effects

As promised, Mozilla officially began rejecting new SHA-1 certificates as of the first of the year. And as promised, there have been some usability issues. Mozilla yesterday said that some security scanners and antivirus products are keeping some from reaching HTTPS websites. “When a user tries t...

CVE-2015-7575

Mozilla Network Security Services NSS before 3.20.2, as used in Mozilla Firefox before 43.0.2 and Firefox ESR 38.x before 38.5.2, does not reject MD5 signatures in Server Key Exchange messages in TLS 1.2 Handshake Protocol traffic, which makes it easier for man-in-the-middle attackers to spoof...

KLA10732 Security bypass vulnerability in Mozilla Firefox and Firefox ESR

Lack of security enforcement was found in Mozilla Firefox. By exploiting this vulnerability malicious users can conduct man-in-the-middle attack. This vulnerability can be exploited remotely via a collision-based attacks. Technical details This vulnerability caused by not rejecting MD5 signatures...

MD5 signatures accepted within TLS 1.2 ServerKeyExchange in server signature — Mozilla

Security researcher Karthikeyan Bhargavan reported an issue in Network Security Services NSS where MD5 signatures in the server signature within the TLS 1.2 ServerKeyExchange message are still accepted. This is an issue since NSS has officially disallowed the accepting MD5 as a hash algorithm in...

NSS -- MD5 downgrade in TLS 1.2 signatures

The Mozilla Project reports: Security researcher Karthikeyan Bhargavan reported an issue in Network Security Services NSS where MD5 signatures in the server signature within the TLS 1.2 ServerKeyExchange message are still accepted. This is an issue since NSS has officially disallowed the acceptin...

rubygem-bundler: 'bundle install' may install a gem from a source other than expected

A flaw was found in the way Bundler handled gems available from multiple sources. An attacker with access to one of the sources could create a malicious gem with the same name, which they could then use to trick a user into installing, potentially resulting in execution of code from the...

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...
