Operating system: Red Hat Linux 6.2 through 7.2
PHP version: 4.1.0
PHP Bug Type: Reproducible crash
Bug description: Red Hat-modified ucd-snmp packages cause php segmentation faults
As described in
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=57421
recent versions (after ~August 2001) of the ucd-snmp packages redefine
sprint_objid and sprint_value at the API and ABI level. PHP's SNMP module
calls both of these functions.
After building PHP 4.1.0 with SNMP support on a stock Red Hat 7.2 system,
the following script dumps core:
<?
$sd = snmpwalk("<device address>", "public", ".iso");
echo $sd;
?>
This affects all systems running Red Hat Linux 6.2 through 7.1 with updated
ucd-snmp packages applied, along with stock 7.2 systems. Someone on the
ethereal-dev mailing list reported that SuSE is affected as well. SNMP
support must be compiled into PHP for it to be affected, of course.
