redhat/expatBuffer Overflow

Risk 18

Severity

Buffer Overflow

AV:N/AC:L/Au:N/C:N/I:N/A:P

Expat is vulnerable to a denial of service, caused by the improper handling of XML data by the big2toUtf8 function within the libexpat library. A remote attacker could exploit this vulnerability using a specially-crafted XML document containing malformed UTF-8 sequences that trigger a buffer over-read to cause the application to crash.
