Red Hat Security Advisory: php security update

Moderate

A vulnerability was found in PHP due to an infinite loop within the phar uncompressor code when processing "quines" gzip files. This vulnerability allows a remote attacker to pass a specially crafted archive to the application, and consume all available system resources, causing a denial of service condition.

CWE-674 - Uncontrolled Recursion

A vulnerability was found in PHP due to the way PHP handles HTTP variable names. It interferes with HTTP variable names that clash with ones that have a specific semantic meaning. This vulnerability allows network and same-site attackers to set a standard insecure cookie in the victim's browser, which is treated as a `__Host-` or `__Secure-` cookie by PHP applications, posing a threat to data integrity.

CWE-20 - Improper Input Validation

An out-of-bounds read flaw was found in PHP due to insufficient input validation in the imageloadfont() function. This flaw allows a remote attacker to pass specially crafted data to the web application, trigger an out-of-bounds read error, and read the contents of memory on the system.

CWE-125 - Out-of-bounds Read

A flaw was found in PHP. This issue occurs due to an uncaught integer overflow in PDO::quote() of PDO_SQLite returning an improperly quoted string. With the implementation of sqlite3_snprintf(), it is possible to force the function to return a single apostrophe if the function is called on user-supplied input without any length restrictions in place.

CWE-190 - Integer Overflow or Wraparound
