Debian Security Advisory

DSA-272-1 dietlibc -- integer overflow

Date Reported:

28 Mar 2003

Affected Packages:

dietlibc

Vulnerable:

Yes

Security database references:

In the Bugtraq database (at SecurityFocus): BugTraq ID 7123.
In Mitre's CVE dictionary: CVE-2003-0028.
CERT's vulnerabilities, advisories and incident notes: VU#516825, CA-2003-10.

More information:

eEye Digital Security discovered an integer overflow in the xdrmem_getbytes() function of glibc, that is also present in dietlibc, a small libc useful especially for small and embedded systems. This function is part of the XDR encoder/decoder derived from Sun's RPC implementation. Depending upon the application, this vulnerability can cause buffer overflows and could possibly be exploited to execute arbitrary code.

For the stable distribution (woody) this problem has been fixed in version 0.12-2.5.

The old stable distribution (potato) does not contain dietlibc packages.

For the unstable distribution (sid) this problem has been fixed in version 0.22-2.

We recommend that you upgrade your dietlibc packages.

Fixed in:

Debian GNU/Linux 3.0 (woody)
