Debian Security Advisory
DSA-098-1 libgtop -- format string vulnerability and buffer overflow
- Date Reported:
- 09 Jan 2002
- Affected Packages:
- libgtop
- Vulnerable:
- Yes
- Security database references:
- In Mitre's CVE dictionary: CVE-2001-0927, CVE-2001-0928.
- More information:
-
Two different problems where found in libgtop-daemon:
- The laboratory intexxia found a format string problem in the logging code from libgtop_daemon. There were two logging functions which are called when authorizing a client which could be exploited by a remote user.
- Flavio Veloso found a buffer overflow in the function that authorizes clients
Since libgtop_daemon runs as user nobody both bugs could be used to gain access as the nobody user to a system running libgtop_daemon.
Both problems have been fixed in version 1.0.6-1.1 and we recommend you upgrade your libgtop-daemon package immediately.
- Fixed in:
-
Debian GNU/Linux 2.2 (potato)
