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 rights 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.
