Ubuntu Security Notice (C) 2005-2013 Canonical, Inc. / NASL script (C) 2006-2013 Tenable Network Security, Inc.
The remote Ubuntu host is missing one or more security-related patches.
An integer overflow was discovered in the exif_process_IFD_TAG()
function in PHP4's EXIF module. EXIF tags with a specially crafted
'Image File Directory' (IFD) tag caused a buffer overflow which could
have been exploited to execute arbitrary code with the privileges of
the PHP4 server. (CAN-2005-1042)
The same module also contained a Denial of Service vulnerability. EXIF
headers with a large IFD nesting level caused an unbound recursion
which would eventually overflow the stack and cause the executed
program to crash. (CAN-2005-1043)
In web applications that automatically process EXIF tags of uploaded
images, both vulnerabilities could be exploited remotely.
Update the affected packages.
