Ubuntu 4.10 : php4 vulnerabilities (USN-112-1)

Ubuntu Security Notice (C) 2005-2013 Canonical, Inc. / NASL script (C) 2006-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

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.

Solution :

Update the affected packages.

Risk factor :

High / CVSS Base Score : 7.5
(CVSS2#AV:N/AC:L/Au:N/C:P/I:P/A:P)
