Description

Multiple vulnerabilities have been discovered in OpenSSL:

CVE-2014-0195 Jueri Aedla discovered that a buffer overflow in processing DTLS fragments could lead to the execution of arbitrary code or denial of service.

CVE-2014-0221 Imre Rad discovered the processing of DTLS hello packets is susceptible to denial of service.

CVE-2014-0224 KIKUCHI Masashi discovered that carefully crafted handshakes can force the use of weak keys, resulting in potential man-in-the-middle attacks.

CVE-2014-3470 Felix Groebert and Ivan Fratric discovered that the implementation of anonymous ECDH ciphersuites is suspectible to denial of service.

be restarted. You can use the tool checkrestart from the package
debian-goodies to detect affected programs or reboot your system. There's
also a forthcoming security update for the Linux kernel later the day
(CVE-2014-3153
), so you need to reboot anyway. Perfect timing, isn't it?

For the unstable distribution (sid), these problems will be fixed soon.

We recommend that you upgrade your openssl packages.");
