Description

Three issues have been found in php5, a server-side, HTML-embedded scripting language.

CVE-2020-7064 A one byte out-of-bounds read, which could potentially lead to information disclosure or crash.

CVE-2020-7066 An URL containing zero (\0) character will be truncated at it, which may cause some software to make incorrect assumptions and possibly send some information to a wrong server.

CVE-2020-7067 Using a malformed url-encoded string an Out-of-Bounds read can occur.

For Debian 8
