VuXML ID fe853666-56ce-11e0-9668-001fd0d616cf
Discovery 2011-03-20
Entry 2011-03-25

US-CERT/NIST reports:

The _zip_name_locate function in zip_name_locate.c in the Zip extension in PHP before 5.3.6 does not properly handle a ZIPARCHIVE::FL_UNCHANGED argument, which might allow context-dependent attackers to cause a denial of service (application crash) via an empty ZIP archive that is processed with a (1) locateName or (2) statName operation.
