Debian Security Advisory
DSA-063-1 xinetd -- change default umask
- Date Reported:
- 17 Jun 2001
- Affected Packages:
- xinetd
- Vulnerable:
- Yes
- Security database references:
- In the Bugtraq database (at SecurityFocus): BugTraq ID 2826, BugTraq ID 2840.
In Mitre's CVE dictionary: CVE-2001-1322, CVE-2001-0763. - More information:
-
zen-parse reported on bugtraq that there is a possible buffer overflow
in the logging code from xinetd. This could be triggered by using a
fake identd that returns special replies when xinetd does an ident
request.
Another problem is that xinetd sets it umask to 0. As a result any programs that xinetd start that are not careful with file permissions will create world-writable files.
Both problems have been fixed in version 2.1.8.8.p3-1.1.
- Fixed in:
-
Debian GNU/Linux 2.2 (potato)
