| Description: | Summary:
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.
Affected Software/OS:
openssl on Debian Linux
Solution:
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?
For the unstable distribution (sid), these problems will be fixed soon.
We recommend that you upgrade your openssl packages.
