Package: login Version: 1:4.0.18.1-5 Severity: important Executing "su" yields an "invalid pointer" error. This is what happens if the password entered is correct:
[EMAIL PROTECTED]:~$ su - root Password: *** glibc detected *** free(): invalid pointer: 0xbfec0120 *** *** glibc detected *** free(): invalid pointer: 0xbfec0120 *** Aborted [EMAIL PROTECTED]:~$ and if the password is incorrect: [EMAIL PROTECTED]:~$ su - root Password: Password: su: Authentication failure *** glibc detected *** free(): invalid pointer: 0xbf8a02a0 *** Aborted [EMAIL PROTECTED]:~$ The same happens if I try to "su" to another user than root; however, logging into root (using ssh) and "su" to another user works. I realise that su may not be at fault, and that another program (such as pam) may be the culprit, but I don't have any lead so far. Setting the environement variable MALLOC_CHECK_=1, as indicated on several web pages after googling for the error, did not help at all. I almost picked an RC severity for this bug, but did not (for now) because I can still login using ssh. This originally happenend with testing; however, I updated the libraries piecewise to unstable to see if it made any difference. Any help welcome !
