DESCRIPTION:
Some vulnerabilities have been discovered in PHP, which can be
exploited by malicious people to cause a DoS (Denial of Service).
1) A NULL pointer dereference error within the "_zip_name_locate()"
function in ext/zip/lib/zip_name_locate.c and can be exploited to
cause a crash when performing certain actions using the "ZipArchive"
class on specially crafted archives.
Successful exploitation requires that the "ZIPARCHIVE::FL_UNCHANGED"
option is used.
2) An error within the "exif_process_IFD_TAG()" function in
ext/exif/exif.c can be exploited to cause a crash when processing
malformed IFD (Image File Descriptor) tags in images with specially
crafted EXIF information.
Successful exploitation requires a 64bit system and may also require
that a large (> 4 GiB) or no memory limit is set via the PHP
"memory_limit" setting.
The vulnerabilities are confirmed in version 5.3.5. Other versions
may also be affected.
SOLUTION:
Fixed in the SVN repository.
