Package : openssl CVE ID : CVE-2016-7056 CVE-2016-8610 CVE-2017-3731

Several vulnerabilities were discovered in OpenSSL:


A local timing attack was discovered against ECDSA P-256.


It was discovered that no limit was imposed on alert packets during
an SSL handshake.


Robert Swiecki discovered that the RC4-MD5 cipher when running on
32 bit systems could be forced into an out-of-bounds read, resulting
in denial of service.

For the stable distribution (jessie), these problems have been fixed in version 1.0.1t-1+deb8u6.

For the unstable distribution (sid), these problems have been fixed in version 1.1.0d-1 of the openssl source package and in version 1.0.2k-1 of the openssl1.0 source package.

We recommend that you upgrade your openssl packages.
