Bug#278278: insecure use of temp files in catchsegv



Package: libc6
Version: 2.3.2.ds1-18
Severity: serious
Tags: security

CAN-2004-0968 describes a bug in the catchsegv program, it uses
temporary files insecurely, which could be vulnerable to a symlink
attack. The version shipped with Debian seems vulnerable, although sinc
it puts the tmp files in the current directory, the program would
probably have to be run in /tmp or another world writable directory to
be exploited.

Redhat has a patch for this, which also includes some changes to
glibcbug, which I did not review.
