SA120 : Truncated Diffie-Hellman Secret Generation in libssh2

SUMMARY Blue Coat products that include affected versions of libssh2 are susceptible to a truncated Diffie-Hellman secret length vulnerability. A remote man-in-the-middle MITM attacker can exploit this vulnerability to intercept SSH connections that originate from Blue Coat products. The MITM...

CVE-2016-3125

The modtls module in ProFTPD before 1.3.5b and 1.3.6 before 1.3.6rc2 does not properly handle the TLSDHParamFile directive, which might cause a weaker than intended Diffie-Hellman DH key to be used and consequently allow attackers to have unspecified impact via unknown vectors...

CVE-2016-3125

ProFTPD mod_tls TLSDHParamFile handling flaw (CVE-2016-3125) may cause a weaker DH key to be used. Affected: ProFTPD before 1.3.5b and before 1.3.6rc2. Remediation: upgrade to 1.3.5b+ or 1.3.6rc2+ (or newer) where patched. Notes from openSUSE/SUSE advisories confirm the fix in later releases.
