Ubuntu Security Notice 6454-4 - Kyle Zeng discovered that the netfilter subsystem in the Linux kernel contained a race condition in IP set operations in certain situations. A local attacker could use this to cause a denial of service. Alex Birnberg discovered that the netfilter subsystem in the Linux kernel did not properly validate register length, leading to an out-of-bounds write vulnerability. A local attacker could possibly use this to cause a denial of service.

Ubuntu Security Notice 6467-1 - Robert Morris discovered that Kerberos did not properly handle memory access when processing RPC data through kadmind, which could lead to the freeing of uninitialized memory. An authenticated remote attacker could possibly use this issue to cause kadmind to crash, resulting in a denial of service.

Ubuntu Security Notice 6403-3 - USN-6403-1 fixed several vulnerabilities in libvpx. This update provides the corresponding update for Ubuntu 16.04 LTS. It was discovered that libvpx did not properly handle certain malformed media files. If an application using libvpx opened a specially crafted file, a remote attacker could cause a denial of service, or possibly execute arbitrary code.

Ubuntu Security Notice 6466-1 - Hyunwoo Kim discovered that the DVB Core driver in the Linux kernel contained a race condition during device removal, leading to a use-after- free vulnerability. A physically proximate attacker could use this to cause a denial of service or possibly execute arbitrary code. Hyunwoo Kim discovered that the Technotrend/Hauppauge USB DEC driver in the Linux kernel did not properly handle device removal events. A physically proximate attacker could use this to cause a denial of service.

The Advanced iFrame plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'advanced_iframe' shortcode in versions up to, and including, 2023.8 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The POWR plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'powr-powr-pack' shortcode in all versions up to, and including, 2.1.0 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

### Summary The handling of named transaction savepoints in all database implementations is vulnerable to [SQL Injection](https://owasp.org/www-community/attacks/SQL_Injection) as user provided input is passed directly to `connection.execute(...)` via f-strings. ### Details An excerpt of the Postgres savepoint handling: ```python async def savepoint(self, name: t.Optional[str] = None) -> Savepoint: name = name or f"savepoint_{self.get_savepoint_id()}" await self.connection.execute(f"SAVEPOINT {name}") return Savepoint(name=name, transaction=self) ``` In this example, we can see user input is directly passed to `connection.execute` without being properly escaped. All implementations of savepoints and savepoint methods directly pass this `name` parameter to `connection.execute` and are vulnerable to this. A non-exhaustive list can be found below: - Postgres - - [One](https://github.com/piccolo-orm/piccolo/blob/master/piccolo/engine/postgres.py#L239) - - [...

Piccolo is an object-relational mapping and query builder which supports asyncio. Prior to version 1.1.1, the handling of named transaction `savepoints` in all database implementations is vulnerable to SQL Injection via f-strings. While the likelihood of an end developer exposing a `savepoints` `name` parameter to a user is highly unlikely, it would not be unheard of. If a malicious user was able to abuse this functionality they would have essentially direct access to the database and the ability to modify data to the level of permissions associated with the database user. A non exhaustive list of actions possible based on database permissions is: Read all data stored in the database, including usernames and password hashes; insert arbitrary data into the database, including modifying existing records; and gain a shell on the underlying server. Version 1.1.1 fixes this issue.
