Debian DSA-4353-1 : php7.0 - security update
High Nessus Plugin ID 119561
SynopsisThe remote Debian host is missing a security-related update.
DescriptionMultiple security issues were found in PHP, a widely-used open source general purpose scripting language: The EXIF module was susceptible to denial of service/information disclosure when parsing malformed images, the Apache module allowed cross-site-scripting via the body of a 'Transfer-Encoding: chunked' request and the IMAP extension performed insufficient input validation which can result in the execution of arbitrary shell commands in the imap_open() function and denial of service in the imap_mail() function.
SolutionUpgrade the php7.0 packages.
For the stable distribution (stretch), these problems have been fixed in version 7.0.33-0+deb9u1.
