Description Enrico Scholz 2006-11-05 15:40:12 UTC 
[This bug is similar but NOT identical to bug #209930 (which was caused by a
misconfiguration of the buildsystem)]

Description of problem:

Applications which are using libltdl are searching '.' for .la files. This can
used by an attacker to execute arbitrary code.

The 'victim.c' example from bug #209930 shows:

| # strace victim
| open("foo.la", O_RDONLY)                = -1 ENOENT (No such file or directory)


Version-Release number of selected component (if applicable):

libtool-ltdl-1.5.22-6.1.i386.rpm
Comment 1 Karsten Hopp 2007-01-23 16:36:05 UTC 
I've disabled this 'feature' in Rawhide
