Affected Packages:

libtomcrypt

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2016-6129.

More information:

It was discovered that the implementation of RSA signature verification in libtomcrypt is vulnerable to the Bleichenbacher signature attack.

If an RSA key with exponent 3 is used it may be possible to forge a PKCS#1 v1.5 signature signed by that key.

For Debian 7 Wheezy, these problems have been fixed in version 1.17-3.2+deb7u1.

We recommend that you upgrade your libtomcrypt packages.
