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

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.
