Description Rimas 2006-11-14 17:43:26 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.0.3705; .NET CLR 1.1.4322; .NET CLR 2.0.50727)

Description of problem:
If /etc/aliases file has aliases of form:

name:  :include:/path

then getaliasbyname("name") glibc function causes segmentation fault when reading such alias.

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

How reproducible:

Steps to Reproduce:
1. Add ":include:" alias to /etc/aliases file, for example:
mylist:  :include:/etc/mail/mylist
2. Create file /etc/mail/mylist with some entries, for example:
3. Write, compile and run such C program:

#include <aliases.h>
#include <stdio.h>

int main() {
  struct aliasent *al = getaliasbyname("mylist");
  if (al) puts("Alias OK!");
  return 0;

Actual Results:
Segmentation fault

Expected Results:
Alias OK!

Additional info:
Same result if I use getent:

# getent aliases mylist
Segmentation fault
