The console runs suid root so these vulnerabilities could be used to run programs as root and gain root access. PLATFORM: Debian GNU/Linux 3.0 (woody) DAMAGE: A local user could exploit one of the buffer overflows to get root access. SOLUTION: Apply updated security packages. ______________________________________________________________________________ VULNERABILITY The risk is MEDIUM. A local user may gain root access. ASSESSMENT: ______________________________________________________________________________ LINKS: CIAC BULLETIN: http://www.ciac.org/ciac/bulletins/o-107.shtml ORIGINAL BULLETIN: http://www.debian.org/security/2004/dsa-472 CVE/CAN: http://www.cve.mitre.org/cgi-bin/cvename.cgi?name= CVE-2003-0648 ______________________________________________________________________________ [***** Start Debian Security Advisory DSA-472-1 *****] Debian Security Advisory DSA-472-1 fte -- several vulnerabilities Date Reported: 03 Apr 2004 Affected Packages: fte Vulnerable: Yes Security database references: In the Debian bugtracking system: Bug 203871. In Mitre's CVE dictionary: CAN-2003-0648. More information: Steve Kemp and Jaguar discovered a number of buffer overflow vulnerabilities in vfte, a version of the fte editor which runs on the Linux console, found in the package fte-console. This program is setuid root in order to perform certain types of low-level operations on the console. Due to these bugs, setuid privilege has been removed from vfte, making it only usable by root. We recommend using the terminal version (in the fte-terminal package) instead, which runs on any capable terminal including the Linux console. For the stable distribution (woody) these problems have been fixed in version 0.49.13-15woody1. For the unstable distribution (sid) these problems have been fixed in version 0.50.0-1.1. We recommend that you update your fte package. Fixed in: Debian GNU/Linux 3.0 (woody) Source: http://security.debian.org/pool/updates/main/f/fte/fte_0.49.13-15woody1.dsc
