Content
VULNERABILITY DETAILS
CVE ID: CVE-2012-1713
DESCRIPTION:
This issue involves a buffer overrun in the Java platform's Font parsing code.
An attacker can potentially place arbitrary data into any location on the host
machine using a maliciously crafted font file.
This issue involves an internal cache in the Java platform's font scaling code,
which may incorrectly be freed from memory by one part of the code (on an error
condition) while it is still in use by another. This scenario will usually lead
to a crash.
An attacker may access arbitrary data within the process address space by
crafting a malicious font with invalid character map (CMAP) data. Specifically,
an attacker can inject an offset which points to a location outside the CMAP
data block.
An attacker is potentially be able to pass execution to arbitrary code under
certain circumstances via a malicious font file containing a specially crafted
hinting program.
