Bug#372696: cupsys: cupsd crashes mysteriously
Package: cupsys
Version: 1.2.1-2
Severity: grave
Justification: renders package unusable
Cupsd crashes occasionally, particularly when browing the web interface.
I compiled from src and ran 'gdb' on the version with all the symbols
still intact, and the problem is near line 2541 on scheduler/dirsvc.c.
The code there reads:
httpAssembleURIf(HTTP_URI_CODING_ALL, uri, sizeof(uri), "ipp", NULL,
iface->hostname, iface->port,
(p->type & CUPS_PRINTER_CLASS) ? "/classes/%s%s" :
"/printers/%s",
p->name);
The two '%s' in the "/classes/" branch are the problem. When trying to
format the second, an invalid address is dereferenced, and BANG.
