CVE-2021-21273 Open redirects on some federation and push requests

Synapse is a Matrix reference homeserver written in python pypi package matrix-synapse. Matrix is an ecosystem for open federated Instant Messaging and VoIP. In Synapse before version 1.25.0, requests to user provided domains were not restricted to external IP addresses when calculating the key...

move_elements can double-free objects on panic

Affected versions of scratchpad used ptr::read to read elements while calling a user provided function f on them. Since the pointer read duplicates ownership, a panic inside the user provided f function could cause a double free when unwinding. The flaw was fixed in commit 891561bea by removing t...

RUSTSEC-2021-0030 move_elements can double-free objects on panic

Affected versions of scratchpad used ptr::read to read elements while calling a user provided function f on them. Since the pointer read duplicates ownership, a panic inside the user provided f function could cause a double free when unwinding. The flaw was fixed in commit 891561bea by removing t...

Tape::take_bytes exposes uninitialized memory to a user-provided Read

Affected versions of this crate passed an unininitialized buffer to a user-provided Read instance in Tape::takebytes. This can result in safe Read implementations reading from the uninitialized buffer leading to undefined behavior. The flaw was corrected in commit 1f2dc7f37dd by removing the unsa...

RUSTSEC-2021-0043 PartialReader passes uninitialized memory to user-provided Read

Affected versions of this crate passed an uniniitalized buffer to a user-provided Read instance in PartialReader::read. This can result in safe Read implementations reading from the uninitialized buffer leading to undefined behavior. The flaw was fixed in commit 39d62c6 by zero-initializing the...

PartialReader passes uninitialized memory to user-provided Read

Design/Logic Flaw

An issue was discovered in the calamine crate before 0.17.0 for Rust. It allows attackers to overwrite heap-memory locations because Vec::setlen is used without proper memory claiming, and this uninitialized memory is used for a user-provided Read operation, as demonstrated by Sectors::get...

CVE-2021-25646 Authenticated users can override system configurations in their requests which allows them to execute arbitrary code.

Apache Druid includes the ability to execute user-provided JavaScript code embedded in various types of requests. This functionality is intended for use in high-trust environments, and is disabled by default. However, in Druid 0.20.0 and earlier, it is possible for an authenticated user to send a...

CVE-2021-26305

An issue was discovered in Deserializer::readvec in the cdr crate before 0.2.4 for Rust. A user-provided Read implementation can gain access to the old contents of newly allocated heap memory, violating soundness...

RUSTSEC-2021-0016 `IoReader::read()`: user-provided `Read` on uninitialized buffer may cause UB

Affected versions of this crate passes an uninitialized buffer to a user-provided Read implementation. Arbitrary Read implementations can read from the uninitialized buffer memory exposure and also can return incorrect number of bytes written to the buffer. Reading from uninitialized memory...

panic safety: double drop may happen within `util::{mutate, mutate2}`

Upon panic in a user-provided function f, fn mutate & fn mutate2 drops twice a same object. Affected versions of this crate did not guard against double drop while temporarily duplicating an object's ownership with ptr::read. Dropping a same object can result in memory corruption. The flaw was...

panic safety: double drop or uninitialized drop of T upon panic

Affected versions of this crate did not guard against potential panics that may happen from user-provided functions T::default and T::drop. Panic within T::default leads to dropping uninitialized T, when it is invoked from common::Slice::::new. Panic within T::drop leads to double drop of T, when...
