OpenSSL < 0.9.8k Multiple Vulnerabilities

Synopsis :

The remote server is affected by multiple vulnerabilities.

Description :

According to its banner, the remote server is running a version of
OpenSSL prior to 0.9.8k. It is, therefore, affected by multiple
vulnerabilities :

- A denial of service vulnerability exists in the
ASN1_STRING_print_ex() function due to improper string
handling. A remote attacker can exploit this to cause an
invalid memory access and application crash.
(CVE-2009-0590)

- A flaw exists in the CMS_verify() function due to
improper handling of errors associated with malformed
signed attributes. A remote attacker can exploit this to
repudiate a signature that originally appeared to be
valid but was actually invalid. (CVE-2009-0591)

- A denial of service vulnerability exists due to improper
handling of malformed ASN.1 structures. A remote
attacker can exploit this to cause an invalid memory
access and application crash. (CVE-2009-0789)

- A memory leak exists in the SSL_free() function in
ssl_lib.c. A remote attacker can exploit this to exhaust
memory resources, resulting in a denial of service
condition. (CVE-2009-5146)
