Subject: [USN-112-1] PHP4 vulnerabilities

===========================================================
Ubuntu Security Notice USN-112-1	     April 14, 2005
php4 vulnerabilities
CAN-2005-1042, CAN-2005-1043
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

libapache2-mod-php4
php4-cgi

The problem can be corrected by upgrading the affected package to
version 4:4.3.8-3ubuntu7.8. After performing a standard system upgrade
you need to reload the PHP module in the webserver by executing

  sudo /etc/init.d/apache2 reload

to effect the necessary changes. 

Details follow:

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.
