According to the project-page "PHKP is an implementation of the OpenPGP HTTP Keyserver Protocol (HKP) in PHP".
I proudly pronounce the first (pre-)release of cryptorecord. Cryptorecords is a ruby gem that provides an API and scripts for creating crypto-related dns-records(e.g. DANE). Currently it supports TLSA, OPENPGPKEYS and SSHFP but I plan to support other records in future. The API doesn't create any keys or certificates. It just takes existing keyfiles to create the DNS-records.
TLS via SMTP is opportunistic which makes connections vulnerable to man-in-the-middle-attacks. In order to prevent mitm-attacks, DANE could be used. The sender-server will first check the domain-records if dnssec is in use(and valid) and if a TLSA-record is published(and valid). If a TLSA-record is valid and matches with the certificate of the recipient-server the connection could be encrypted and the encryption is verified.
DNS is one of the oldest but also one of the most important network protocols we have and actively use. Dan Kaminsky discovered 2008 some serious flaws in DNS which is very well explained on this site. DNSsec is supposed to solve those problems.
Impact: Code-Execution. The impact for this vulnerability is considered as low because an attacker could exploit this for code execution only if the configuration-file is not protected properly.

A few months ago I published a vulnerability in OpenElecs updater. I successfully hacked remotely OpenElec version 6.x.x and 7.x.x . OpenElec 8 is available for a while and reached version 8.0.4. So I tested the bug against this version and it's still open. An attacker who is Man-In-The-Middle can remotely compromise Openelec-Updates and plant a reverse-shell on the target.
Eric Dumazet of Google found a very dangerous remote execution bug in the Linux Kernel. It's located in the recv-syscall with the MSG_PEEK-flag set. Attackers can remotely execute code on the target..
I used a google-dork to find vulnerable software:
MSG_PEEK filetype:c
And found some possible targets:
The latest wikileaks revealings gave also insights about an interesting bug in cisco products. No I am not talking about the bug in the Cisco Cluster Management Protocol (CMP). I am talking about the open telnet ports.Ten years ago it was already recommended to use ssh instead and there are still so many devices out t
During my research about update mechanisms of open-source software I discovered vulnerabilities in OpenElec.
