CVE-2017-3731
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.");
