Ubuntu September 7, 2026

PHP could be made to crash or expose sensitive information if it received specially crafted input.

php7.0 - HTML-embedded scripting language interpreter

It was discovered that PHP incorrectly handled Apache map decoding in SOAP servers with a typemap configured. A remote attacker could use this issue to cause a NULL pointer dereference, resulting in a denial of service. ( CVE-2026-7262 ) It was discovered that PHP incorrectly handled signed integer overflow in the metaphone() function. An attacker could use this issue to cause an out-of-bounds read, resulting in a denial of service. ( CVE-2026-7568 ) It was discovered that PHP incorrectly handled circular symbolic links in phar archives. An attacker could use this issue to cause unbounded recursion, resulting in a denial of service. ( CVE-2026-7260 ) It was discovered that PHP incorrectly escaped backslashes in the pgsql extension when standard_conforming_strings is enabled. An attacker could use this issue to...

In general, a standard system update will make all the necessary changes.

The problem can be corrected by updating your system to the following package versions:
