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...

DEBIAN-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...

CVE-2015-7575

CVE-2015-7575 affects NSS (used by Mozilla Firefox) where MD5 signatures in TLS 1.2 ServerKeyExchange are accepted, enabling potential MITM server impersonation. The published description notes NSS before 3.20.2 and Firefox before 43.0.2 / ESR 38.x before 38.5.2 are impacted. Debian/IBM/AIX advis...

Automated DeAuth Attack: zizzania

zizzania sniffs wireless traffic listening for WPA handshakes and dumping only those frames suitable to be decrypted one beacon + EAPOL frames + data. In order to speed up the process, zizzania sends IEEE 802.11 DeAuth frames to the stations whose handshake is needed, properly handling...

mbedTLS/PolarSSL -- SLOTH attack on TLS 1.2 server authentication

ARM Limited reports: MD5 handshake signatures in TLS 1.2 are vulnerable to the SLOTH attack on TLS 1.2 server authentication. They have been disabled by default. Other attacks from the SLOTH paper do not apply to any version of mbed TLS or PolarSSL...

Small subgroup attack in Mozilla NSS

tl;dr While the TLS servers attacks has been pretty much studied and fixed see e.g. https://www.secure-resumption.com/ and https://weakdh.org/ the situation with the TLS clients is was not ideal and can be improved. Here I report a Small subgroup attack for TLS clients that I performed against...
