Package: aatv
Version: 0.3-3
Severity: normal

*** Please type your report below this line ***

  aatv contains code which causes a buffer overflow when reading
 an overly long $HOME variable.

  This is exploitable to execute arbitary code, but not usefully since
 it is neither setuid nor setgid.

  Demonstration:

  [EMAIL PROTECTED]:~$ HOME=`perl -e "print 'x'x3000"` aatv
  Segmentation fault
  [EMAIL PROTECTED]:~$

  Code (aatv.c):
    sprintf (filename, "%s/%s", getenv ("HOME"), ".aatv");


  Fix:
    snprintf (filename, sizeof(filename)-1, "%s/%s", getenv ("HOME"), ".aatv");
