Heartbleed bug in OpenSSL is major security risk

Post by zme-ul »

The Heartbleed Bug is a serious vulnerability in the popular OpenSSL cryptographic software library. This weakness allows stealing the information protected, under normal conditions, by the SSL/TLS encryption used to secure the Internet. SSL/TLS provides communication security and privacy over the Internet for applications such as web, email, instant messaging (IM) and some virtual private networks (VPNs).

The Heartbleed bug allows anyone on the Internet to read the memory of the systems protected by the vulnerable versions of the OpenSSL software. This compromises the secret keys used to identify the service providers and to encrypt the traffic, the names and passwords of the users and the actual content. This allows attackers to eavesdrop communications, steal data directly from the services and users and to impersonate services and users.

din cate stiu si am gasit pana acum, Valve, Google, Yahoo, Flickr, Imgur au fost la un momendat vulnerabile la acest exploit

Sa le f** neamu alora care au gasit Heartbleed-u si l-au exploatat ca mi-a luat o zi jumate sa rezolv problema pe unde sunt webmaster/sysadmin. De ce nu vrea lumea sa foloseasca Cloudflare, nu inteleg (folosesc pentru site-urile mele si ei au rezolvat problemele cu vreo saptamana inainte sa se face publice toate magariile), mai ales cand au si servicii free

The Programmer Behind Heartbleed Speaks Out: It Was an Accident
The Internet bug known as Heartbleed was introduced to the world on New Year's Eve in December 2011. Now, one of the people involved is sharing his side of the story.

Programmer Robin Seggelmann says he wrote the code for the part of OpenSSL that led to Heartbleed. But it was an accident. He submitted the code to the OpenSSL project and other members reviewed it. Seggelmann later added another piece of code for a new feature, which the members then added. It was this added feature that introduced the bug.

Seggelmann told the Sydney Morning Herald that the actual error was "trivial," but that its impact was clearly severe. Since he and the reviewers missed the flaw, it eventually made its way to the official release, which went live on Dec. 31, 2011, according to logs.

Heartbleed is a vulnerability in the encryption that many sites use to ensure that your communications can't be intercepted. Theoretically, up to two-thirds of the Internet traffic was exposed for more than two years. Engineers at security firm Codenomicon discovered the flaw last week, and it was publicly announced on April 7.

mama lor! de mai mult 3 ani de zile exista vulnerabilitatea asta

nivelul2.lab501.ro uses an invalid security certificate. The certificate is not trusted because it is self-signed. The certificate is only valid for web1.lab501.ro The certificate expired on 27-Aug-13 11:04. The current time is 11-Apr-14 16:23.

uitat sa adaug,
daca aveti pe router FW custom DDWRT (all versions between ~19000 - 23882 are affected, previous releases should be fine, but they have other vulnerabilities ) sau OpenWRT, update the fucker naw! ;)
DD-WRT started using the vulnerable code on 2012/04/29. Any DD-WRT build after (and including) 19163 has the flaw, and any build after (and including) 23882 has the fix.

openssl is used for freeradius, openvpn, tor, asterisk
