Additional cryptographic weaknesses in the krb4implementation permit the use of cut-and-paste attacks to fabricatekrb4 tickets for unauthorized client principals if triple-DES keys areused to key krb4 services. These attacks can subvert a site's entireKerberos authentication infrastructure.This version of the heimdal package changes the default behavior anddisallows cross-realm authentication for Kerberos version 4. Becauseof the fundamental nature of the problem, cross-realm authenticationin Kerberos version 4 cannot be made secure and sites should avoid itsuse. A new option (--kerberos4-cross-realm) is provided to the kdccommand to re-enable version 4 cross-realm authentication for thosesites that must use this functionality but desire the other securityfixes.For the stable distribution (woody) this problem has beenfixed in version 0.4e-7.woody.6The old stable distribution (potato) is not affected by this problem,since it isn't compiled against kerberos 4.For the unstable distribution (sid) this problem has beenfixed in version 0.5.2-1.We recommend that you upgrade your heimdal packages imediately.Solution:https://secure1.securityspace.com/smysecure/catid.html?in=DSA%20269-1Risk factor : High"; script_description(english:desc["english"]); summary["english"] = "Debian Security Advisory DSA 269-1 (heimdal)"; script_summary(english:summary["english"]); script_category(ACT_GATHER_INFO); script_copyright(english:"Copyright (c) 2005 E-Soft Inc. http://www.securityspace.com"); family["english"] = "Debian Local Security Checks"; script_family(english:family["english"]); script_dependencies("gather-package-list.nasl"); script_require_keys("ssh/login/packages"); exit(0);}## The script code starts here#include("revisions-lib.inc");include("pkg-lib-deb.inc");vuln = 0;if(isdpkgvuln(pkg:"heimdal-docs", ver:"0.4e-7.woody.6", rls:"DEB3.0")) { vuln = 1;}if(isdpkgvuln(pkg:"heimdal-lib", ver:"0.4e-7.woody.6", rls:"DEB3.0")) { vuln = 1;}if(isdpkgvuln(pkg:"heimdal-clients", ver:"0.4e-7.woody.6", rls:"DEB3.0")) { vuln = 1;}if(isdpkgvuln(pkg:"heimdal-clients-x", ver:"0.4e-7.woody.6", rls:"DEB3.0")) { vuln = 1;}if(isdpkgvuln(pkg:"heimdal-dev", ver:"0.4e-7.woody.6", rls:"DEB3.0")) { vuln = 1;}if(isdpkgvuln(pkg:"heimdal-kdc", ver:"0.4e-7.woody.6", rls:"DEB3.0")) { vuln = 1;}if(isdpkgvuln(pkg:"heimdal-servers", ver:"0.4e-7.woody.6", rls:"DEB3.0")) { vuln = 1;}if(isdpkgvuln(pkg:"heimdal-servers-x", ver:"0.4e-7.woody.6", rls:"DEB3.0")) { vuln = 1;}if(isdpkgvuln(pkg:"libasn1-5-heimdal", ver:"0.4e-7.woody.6", rls:"DEB3.0")) { vuln = 1;}if(isdpkgvuln(pkg:"libcomerr1-heimdal", ver:"0.4e-7.woody.6", rls:"DEB3.0")) { vuln = 1;}if(isdpkgvuln(pkg:"libgssapi1-heimdal", ver:"0.4e-7.woody.6", rls:"DEB3.0")) { vuln = 1;}if(isdpkgvuln(pkg:"libhdb7-heimdal", ver:"0.4e-7.woody.6", rls:"DEB3.0")) { vuln = 1;}if(isdpkgvuln(pkg:"libkadm5clnt4-heimdal", ver:"0.4e-7.woody.6", rls:"DEB3.0")) { vuln = 1;}if(isdpkgvuln(pkg:"libkadm5srv7-heimdal", ver:"0.4e-7.woody.6", rls:"DEB3.0")) { vuln = 1;}if(isdpkgvuln(pkg:"libkafs0-heimdal", ver:"0.4e-7.woody.6", rls:"DEB3.0")) { vuln = 1;}if(isdpkgvuln(pkg:"libkrb5-17-heimdal", ver:"0.4e-7.woody.6", rls:"DEB3.0")) { vuln = 1;}if(isdpkgvuln(pkg:"libotp0-heimdal", ver:"0.4e-7.woody.6", rls:"DEB3.0")) { vuln = 1;}if(isdpkgvuln(pkg:"libroken9-heimdal", ver:"0.4e-7.woody.6", rls:"DEB3.0")) { vuln = 1;}if(isdpkgvuln(pkg:"libsl0-heimdal", ver:"0.4e-7.woody.6", rls:"DEB3.0")) { vuln = 1;}if(isdpkgvuln(pkg:"libss0-heimdal", ver:"0.4e-7.woody.6", rls:"DEB3.0")) { vuln = 1;}if(vuln) { security_hole(0);}
