What is CVE-2006-7140?
CVE-2006-7140 is a medium-severity vulnerability in Sun Solaris, published on 7 Mar 2007. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
The libike library, as used by in.iked, elfsign, and kcfd in Sun Solaris 9 and 10, when using an RSA key with exponent 3, removes PKCS-1 padding before generating a hash, which allows remote attackers to forge a PKCS #1 v1.5 signature that is signed by that RSA key and prevents libike from correctly verifying X.509 and other certificates that use PKCS #1, a similar issue to CVE-2006-4339.
