Synopsis

The remote web server has multiple SSL-related vulnerabilities.

 

Vulnerability Description

According 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. (CVE-2009-3245)
  • 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.

 

Solution

Upgrade to OpenSSL 0.9.8m or later.
