Subject: [USN-4-1] Standard C library script vulnerabilities

===========================================================
Ubuntu Security Notice USN-4-1             October 27, 2004
Standard C library script vulnerabilities
CAN-2004-0968
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

libc6

The problem can be corrected by upgrading the affected package to
version 2.3.2.ds1-13ubuntu2.2. In general, a standard system upgrade
is sufficient to effect the necessary changes.

Details follow:

Recently, Trustix Secure Linux discovered some vulnerabilities in the
libc6 package. The utilities "catchsegv" and "glibcbug" created
temporary files in an insecure way, which allowed a symlink attack to
create or overwrite arbitrary files with the privileges of the user
invoking the program.
