paul Posted July 7, 2010 Report Share Posted July 7, 2010 Multiple vulnerabilities has been found and corrected in heimdal: The (1) krshd and (2) v4rcp applications in (a) MIT Kerberos 5 (krb5) up to 1.5, and 1.4.x before 1.4.4, when running on Linux and AIX, and (B) Heimdal 0.7.2 and earlier, do not check return codes for setuid calls, which allows local users to gain privileges by causing setuid to fail to drop privileges using attacks such as resource exhaustion (CVE-2006-3083). The (1) ftpd and (2) ksu programs in (a) MIT Kerberos 5 (krb5) up to 1.5, and 1.4.x before 1.4.4, and (B) Heimdal 0.7.2 and earlier, do not check return codes for setuid calls, which might allow local users to gain privileges by causing setuid to fail to drop privileges. NOTE: as of 20060808, it is not known whether an exploitable attack scenario exists for these issues (CVE-2006-3084). Certain invalid GSS-API tokens can cause a GSS-API acceptor (server) to crash due to a null pointer dereference in the GSS-API library (CVE-2010-1321). The updated packages have been patched to correct these issues. Link to comment Share on other sites More sharing options...
