SynopsisThe remote web server has multiple SSL-related vulnerabilities.
DescriptionAccording to its banner, the remote web server uses a version of OpenSSL older than 0.9.8m. Such versions have the following vulnerabilities :
- Session renegotiations are not handled properly, which could be exploited to insert arbitrary plaintext by a man-in-the-middle. (CVE-2009-3555)
- The library does not check for a NULL return value from calls to the bn_wexpand() function, which has unspecified impact.
- A memory leak in the zlib_stateful_finish function in crypto/comp/c_zlib.c allows remote attackers to cause a denial of service via vectors that trigger incorrect calls to the CRYPTO_cleanup_all_ex_data function.
(CVE-2008-1678, CVE-2009-4355) For this vulnerability to be exploitable, compression must be enabled in OpenSSL for SSL/TLS connections.
SolutionUpgrade to OpenSSL 0.9.8m or later.
