Categoría:	Mandrake Local Security Checks
Título:	Mandrake Security Advisory MDKSA-2003:098 (openssl)
Resumen:	NOSUMMARY
Descripción:	Description: The remote host is missing an update to openssl announced via advisory MDKSA-2003:098. Two bugs were discovered in OpenSSL 0.9.6 and 0.9.7 by NISCC. The parsing of unusual ASN.1 tag values can cause OpenSSL to crash, which could be triggered by a remote attacker by sending a carefully-crafted SSL client certificate to an application. Depending upon the application targetted, the effects seen will vary in some cases a DoS (Denial of Service) could be performed, in others nothing noticeable or adverse may happen. These two vulnerabilities have been assigned CVE-2003-0543 and CVE-2003-0544. Additionally, NISCC discovered a third bug in OpenSSL 0.9.7. Certain ASN.1 encodings that are rejected as invalid by the parser can trigger a bug in deallocation of a structure, leading to a double free. This can be triggered by a remote attacker by sending a carefully-crafted SSL client certificate to an application. This vulnerability may be exploitable to execute arbitrary code. This vulnerability has been assigned CVE-2003-0545. The packages provided have been built with patches provided by the OpenSSL group that resolve these issues. A number of server applications such as OpenSSH and Apache that make use of OpenSSL need to be restarted after the update has been applied to ensure that they are protected from these issues. Users are encouraged to restart all of these services or reboot their systems. Affected versions: 8.2, 9.0, 9.1, 9.2, Corporate Server 2.1, Multi Network Firewall 8.2 Solution: To upgrade automatically use MandrakeUpdate or urpmi. The verification of md5 checksums and GPG signatures is performed automatically for you. http://www.securityspace.com/smysecure/catid.html?in=MDKSA-2003:098 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2003-0543 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2003-0544 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2003-0545 http://www.kb.cert.org/vuls/id/255484 http://www.kb.cert.org/vuls/id/380864 http://www.kb.cert.org/vuls/id/935264 http://www.openssl.org/news/secadv_20030930.txt http://www.uniras.gov.uk/vuls/2003/006489/tls.htm http://www.uniras.gov.uk/vuls/2003/006489/openssl.htm Risk factor : Critical CVSS Score: 10.0
