RHSA-2010:0679: Moderate: rpm security and bug fix update

The RPM Package Manager (RPM) is a command line driven package managementsystem capable of installing, uninstalling, verifying, querying, andupdating software packages.It was discovered that RPM did not remove setuid and setgid bits set onbinaries when upgrading packages. A local attacker able to create hardlinks to binaries could use this flaw to keep those binaries on the system,at a specific version level and with the setuid or setgid bit set, even ifthe package providing them was upgraded by a system administrator. Thiscould have security implications if a package was upgraded because of asecurity flaw in a setuid or setgid program. (CVE-2010-2059)This update also fixes the following bug: A memory leak in the communication between RPM and the Security-Enhanced Linux (SELinux) subsystem, which could have caused extensive memoryconsumption. In reported cases, this issue was triggered by runningrhncheck when errata were scheduled to be applied. (BZ#627630)All users of rpm are advised to upgrade to these updated packages, whichcontain backported patches to correct these issues.
