Debian DSA-2950-1 : openssl - security update

high Nessus Plugin ID 74337
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Debian host is missing a security-related update.


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.

Upgrade the openssl packages.

For the stable distribution (wheezy), these problems have been fixed in version 1.0.1e-2+deb7u10. All applications linked to openssl need to 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?
