SynopsisThe remote web server is running an outdated instance of OpenSSL and that is affected by multiple vulnerabilities.
DescriptionAccording to its banner, the version of OpenSSL on the remote host is 1.0.2 prior to 1.0.2e and is affected by the following vulnerabilities :
- A flaw in the 'ssl3_get_key_exchange()' function in 'ssl/s3_clnt.c' is triggered when handling a 'ServerKeyExchange' for an anon DH ciphersuite with the value of 'p' set to 0. This may allow a context-dependent attacker to crash an application linked against the library. (CVE-2015-1794)
- A carry propagating flaw exists within the x86_64 Montgomery squaring procedure. This may cause 'BN_mod_exp' to produce incorrect results, which may potentially allow an attacker to derive information regarding private keys. (CVE-2015-3193)
SolutionUpgrade OpenSSL to version 1.0.2e or higher
