New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 5.9
SynopsisThe remote Mandrake Linux host is missing one or more security updates.
DescriptionDr S N Henson of the OpenSSL core team and Open Network Security recently developed an ASN1 test suite for NISCC (www.niscc.gov.uk).
When the test suite was run against OpenSSL two denial of service vulnerabilities were discovered.
During the parsing of certain invalid ASN1 structures an error condition is mishandled. This can result in an infinite loop which consumes system memory. (CVE-2006-2937)
Certain types of public key can take disproportionate amounts of time to process. This could be used by an attacker in a denial of service attack. (CVE-2006-2940)
Tavis Ormandy and Will Drewry of the Google Security Team discovered a buffer overflow in the SSL_get_shared_ciphers utility function, used by some applications such as exim and mysql. An attacker could send a list of ciphers that would overrun a buffer. (CVE-2006-3738)
Tavis Ormandy and Will Drewry of the Google Security Team discovered a possible DoS in the sslv2 client code. Where a client application uses OpenSSL to make a SSLv2 connection to a malicious server that server could cause the client to crash. (CVE-2006-4343)
Updated packages are patched to address these issues.
There was an error in the original published patches for CVE-2006-2940. New packages have corrected this issue.
SolutionUpdate the affected packages.
