DEBIAN-CVE-2015-7969
Multiple memory leaks in Xen 4.0 through 4.6.x allow local guest administrators or domains with certain permission to cause a denial of service memory consumption via a large number of "teardowns" of domains with the vcpu pointer array allocated using the 1 XENDOMCTLmaxvcpus hypercall or the...
Flawed TLS Implementations Leak RSA Keys
A number of TLS software implementations contain vulnerabilities that allow hackers with minimal computational expense to learn RSA keys. Florian Weimer, a researcher with Red Hat, last week published a paper called “Factoring RSA Keys With TLS Perfect Forward Secrecy” that demonstrated...
IVRE - A Python network recon framework, based on Nmap, Bro & p0f
IVRE Instrument de veille sur les réseaux extérieurs or DRUNK Dynamic Recon of UNKnown networks is a network recon framework, including two modules for passive recon one p0f-based and one Bro-based and one module for active recon mostly Nmap-based, with a bit of ZMap. The advertising slogans are:...
LOGJAM: TLS connections which support export grade DHE key-exchange are vulnerable to MITM attacks
A flaw was found in the way the TLS protocol composes the Diffie-Hellman exchange for both export and non-export grade cipher suites. An attacker could use this flaw to downgrade a DHE connection to use export-grade key sizes, which could then be broken by sufficient pre-computation. This can lea...

Logjam attacks-the new encryption bug affects a large number of users-bug warning-the black bar safety net
Diffie-Hellman key exchange technology is one of the popular encryption algorithm which allows the Internet Protocol uses a shared key and a secure link. It is a multi-Protocol based including HTTPS, SSH, IPsec, SMTPS and some rely on the TLS Protocol. We have found a number of Diffie-Hellman key...
SQLassie - Effective Database Security
SQLassie is a free MySQL database firewall that prevents SQL injection attacks at runtime. SQLassie uses Bayesian classifiers to determine the likelihood of a query being an attack. This approach produces fewer false positives than other similar approaches. Security SQLassie prevents injection...
New MySQL Bug Can Strip SSL Protection From Connections
Researchers have identified a serious vulnerability in some versions of Oracle’s MySQL database product that allows an attacker to strip SSL/TLS connections of their security wrapping transparently. The vulnerability is the result of the way that an option in MySQL handles requests for secure...
