Ubuntu Security Notice 6155-1 - Dennis Brinkrolf and Tobias Funke discovered that Requests incorrectly leaked Proxy-Authorization headers. A remote attacker could possibly use this issue to obtain sensitive information.

Requests is a HTTP library. Since Requests 2.3.0, Requests has been leaking Proxy-Authorization headers to destination servers when redirected to an HTTPS endpoint. This is a product of how we use `rebuild_proxies` to reattach the `Proxy-Authorization` header to requests. For HTTP connections sent through the tunnel, the proxy will identify the header in the request itself and remove it prior to forwarding to the destination server. However when sent over HTTPS, the `Proxy-Authorization` header must be sent in the CONNECT request as the proxy has no visibility into the tunneled request. This results in Requests forwarding proxy credentials to the destination server unintentionally, allowing a malicious actor to potentially exfiltrate sensitive information. This issue has been patched in version 2.31.0.

### Impact Since Requests v2.3.0, Requests has been vulnerable to potentially leaking `Proxy-Authorization` headers to destination servers, specifically during redirects to an HTTPS origin. This is a product of how `rebuild_proxies` is used to recompute and [reattach the `Proxy-Authorization` header](https://github.com/psf/requests/blob/f2629e9e3c7ce3c3c8c025bcd8db551101cbc773/requests/sessions.py#L319-L328) to requests when redirected. Note this behavior has _only_ been observed to affect proxied requests when credentials are supplied in the URL user information component (e.g. `https://username:password@proxy:8080`). **Current vulnerable behavior(s):** 1. HTTP → HTTPS: **leak** 2. HTTPS → HTTP: **no leak** 3. HTTPS → HTTPS: **leak** 4. HTTP → HTTP: **no leak** For HTTP connections sent through the proxy, the proxy will identify the header in the request itself and remove it prior to forwarding to the destination server. However when sent over HTTPS, the `Proxy-Authorization` head...

Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Hotspot). Supported versions that are affected are Oracle Java SE: 8u361, 8u361-perf, 11.0.18, 17.0.6; Oracle GraalVM Enterprise Edition: 20.3.9, 21.3.5 and 22.3.1. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Java SE, Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability can also be exploited by using APIs in the specified Component, e.g., through...

cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. In affected versions `Cipher.update_into` would accept Python objects which implement the buffer protocol, but provide only immutable buffers. This would allow immutable objects (such as `bytes`) to be mutated, thus violating fundamental rules of Python and resulting in corrupted output. This now correctly raises an exception. This issue has been present since `update_into` was originally introduced in cryptography 1.8.

Previously, `Cipher.update_into` would accept Python objects which implement the buffer protocol, but provide only immutable buffers: ```pycon >>> outbuf = b"\x00" * 32 >>> c = ciphers.Cipher(AES(b"\x00" * 32), modes.ECB()).encryptor() >>> c.update_into(b"\x00" * 16, outbuf) 16 >>> outbuf b'\xdc\x95\xc0x\xa2@\x89\x89\xadH\xa2\x14\x92\x84 \x87\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00' ``` This would allow immutable objects (such as `bytes`) to be mutated, thus violating fundamental rules of Python. This is a soundness bug -- it allows programmers to misuse an API, it cannot be exploited by attacker controlled data alone. This now correctly raises an exception. This issue has been present since `update_into` was originally introduced in cryptography 1.8.
