CVE-2022-31631

Due to an uncaught integer overflow, PDO::quote() of PDO_SQLite may return an improperly quoted string. The exact details likely depend on the implementation of sqlite3_snprintf(), but with some versions 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.

CVE-2023-0567

Tim Dusterhus discovered that malformed BCrypt hashes that include a $ character within their salt part trigger a buffer overread and may erroneously validate any password as valid. (Password_verify() always returns true with such inputs.)

CVE-2023-0568

1-byte array overrun when appending slash to paths during path resolution.

CVE-2023-0662

Jakob Ackermann discovered a Denial of Service vulnerability when parsing multipart request body: the request body parsing in PHP allows any unauthenticated attacker to consume a large amount of CPU time and trigger excessive logging.

For Debian 10 buster, these problems have been fixed in version 7.3.31-1~deb10u3.

We recommend that you upgrade your php7.3 packages.

For the detailed security status of php7.3 please refer to its security tracker page at: [link moved to references]

Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references]");
