Description zweers 2001-03-02 05:39:31 UTC

pop3 and imap from cyrus-imapd consistently seg fault when they reach line
128 in common.c.

My system is using pam for authentication with openldap.

The offending line is:

lib/common.c:128  *out=sasl_ALLOC(len + 1);

sasl_ALLOC is defined here:

lib/saslint:135 #define sasl_ALLOC(__size__)
(_sasl_allocation_utils.malloc((__size__)))

The value of _sasl_allocation_utils.malloc appears to be set in the
declaration of the variable in lib/common.c:79 but for some reason its
value appears to be changed.

My quick work around was to replace the offending line with a direct malloc
call.  So far, this has fixed the problem.

(gdb) p _sasl_allocation_utils.calloc
$6 = (void *(*)(long unsigned int, long unsigned int)) 0x804eb10 <calloc>
(gdb) p _sasl_allocation_utils.malloc
$7 = (void *(*)(long unsigned int)) 0x80630b0 <strcpy+82720>

I ran gdb /usr/cyrus/bin/pop3d after the connection had already been
started.  I added a watch for these two values, and their values are
changed as the program is run.

The source files that I mention here are all part of the cyrus-sasl package. 
cyrus-imapd is that package that the problem would appear in, but only when
using the cyrus-sasl lib's.

Red Hat apologizes that these issues were not resolved in a more

Thanks again for your help.
