Linux Distros Unpatched Vulnerability : CVE-2006-10003

critical Nessus Plugin ID 303057

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - XML::Parser versions through 2.47 for Perl has an off-by-one heap buffer overflow in st_serial_stack. In the case (stackptr == stacksize - 1), the stack will NOT be expanded. Then the new value will be written at location (++stackptr), which equals stacksize and therefore falls just outside the allocated buffer.
 The bug can be observed when parsing an XML file with very deep element nesting (CVE-2006-10003)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
