Test ID:	1.3.6.1.4.1.25623.1.0.52076
Category:	Ubuntu Local Security Checks
Title:	Ubuntu 4.10 USN-112-1 (php4)
Summary:	Ubuntu 4.10 USN-112-1 (php4)
Description:	The remote host is missing an update to php4 announced via advisory USN-112-1. 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. (CVE-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. (CVE-2005-1043) In web applications that automatically process EXIF tags of uploaded images, both vulnerabilities could be exploited remotely. The following packages are affected: libapache2-mod-php4 php4-cgi Solution: 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. http://www.securityspace.com/smysecure/catid.html?in=USN-112-1 Risk factor : High
