Test ID:	1.3.6.1.4.1.25623.1.0.51466
Category:	Conectiva Local Security Checks
Title:	Conectiva Security Advisory CLA-2003:751
Summary:	NOSUMMARY
Description:	Description: The remote host is missing updates announced in advisory CLA-2003:751. OpenSSL[1] implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as full-strength general purpose cryptography functions. It is used (as a library) by several projects, like Apache, OpenSSH, Bind, OpenLDAP and many others clients and servers programs. NISCC[2] developed a test suit to verify the behavior of SSL and TLS implementations when presented with malformed client certificates. As a result of this test, the following vulnerabilities[3,4] were found in the OpenSSL implementation: - Vulnerabilities in the handling of malformed ASN.1 tags (CVE-2003-0543[5] and CVE-2003-0544[6]). Because of a flaw in the handling of ASN.1 tag values, an out-of-bounds read can be triggered in some situations. A remote attacker can exploit these vulnerabilities to cause a denial of service condition. - Stack corruption in the handling of rejected ASN.1 encodings (CVE-2003-0545[7]). A remote attacker may exploit this vulnerability to cause a denial of service condition and potentially execute arbitrary code. This vulnerability does not affect the OpenSSL versions distributed with Conectiva Linux 7.0 and 8 (OpenSSL-0.9.6). Additionally, this update includes fixes for a bug which causes OpenSSL to parse a client certificate when it should reject it as a protocol error. Solution: The apt tool can be used to perform RPM package upgrades by running 'apt-get update' followed by 'apt-get upgrade' http://www.openssl.org http://www.niscc.gov.uk/aboutniscc/index.htm http://www.uniras.gov.uk/vuls/2003/006489/openssl.htm http://www.openssl.org/news/secadv_20030930.txt 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.securityspace.com/smysecure/catid.html?in=CLA-2003:751 http://distro.conectiva.com.br/atualizacoes/index.php?id=a&anuncio=002003 Risk factor : Critical CVSS Score: 10.0
