Ubuntu Security Notice 6623-1 - It was discovered that Django incorrectly handled certain inputs that uses intcomma template filter. An attacker could possibly use this issue to cause a denial of service.

An issue was discovered in Django 3.2 before 3.2.24, 4.2 before 4.2.10, and Django 5.0 before 5.0.2. The intcomma template filter was subject to a potential denial-of-service attack when used with very long strings.

Ubuntu Security Notice 6618-1 - It was discovered that Pillow incorrectly handled certain long text arguments. An attacker could possibly use this issue to cause Pillow to consume resources, leading to a denial of service. This issue only affected Ubuntu 20.04 LTS, and Ubuntu 22.04 LTS. Duarte Santos discovered that Pillow incorrectly handled the environment parameter to PIL.ImageMath.eval. An attacker could possibly use this issue to execute arbitrary code.

Ubuntu Security Notice 6599-1 - Yeting Li discovered that Jinja incorrectly handled certain regex. An attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 14.04 LTS, Ubuntu 18.04 LTS, and Ubuntu 20.04 LTS. It was discovered that Jinja incorrectly handled certain HTML passed with xmlatter filter. An attacker could inject arbitrary HTML attributes keys and values potentially leading to XSS.

Red Hat Security Advisory 2024-0345-03 - An update for python-pillow is now available for Red Hat Enterprise Linux 7.

Ubuntu Security Notice 6595-1 - It was discovered that PyCryptodome had a timing side-channel when performing OAEP decryption. A remote attacker could possibly use this issue to recover sensitive information.

The `xmlattr` filter in affected versions of Jinja accepts keys containing spaces. XML/HTML attributes cannot contain spaces, as each would then be interpreted as a separate attribute. If an application accepts keys (as opposed to only values) as user input, and renders these in pages that other users see as well, an attacker could use this to inject other attributes and perform XSS. Note that accepting keys as user input is not common or a particularly intended use case of the `xmlattr` filter, and an application doing so should already be verifying what keys are provided regardless of this fix.

PyCryptodome and pycryptodomex before 3.19.1 allow side-channel leakage for OAEP decryption, exploitable for a Manger attack.

aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. Improper validation made it possible for an attacker to modify the HTTP request (e.g. to insert a new header) or create a new HTTP request if the attacker controls the HTTP version. The vulnerability only occurs if the attacker can control the HTTP version of the request. This issue has been patched in version 3.9.0.

aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. Improper validation makes it possible for an attacker to modify the HTTP request (e.g. insert a new header) or even create a new HTTP request if the attacker controls the HTTP method. The vulnerability occurs only if the attacker can control the HTTP method (GET, POST etc.) of the request. If the attacker can control the HTTP version of the request it will be able to modify the request (request smuggling). This issue has been patched in version 3.9.0.

### Summary Improper validation make it possible for an attacker to modify the HTTP request (e.g. to insert a new header) or even create a new HTTP request if the attacker controls the HTTP version. ### Details The vulnerability only occurs if the attacker can control the HTTP version of the request (including its type). For example if an unvalidated JSON value is used as a version and the attacker is then able to pass an array as the `version` parameter. Furthermore, the vulnerability only occurs when the `Connection` header is passed to the `headers` parameter. At this point, the library will use the parsed value to create the request. If a list is passed, then it bypasses validation and it is possible to perform CRLF injection. ### PoC The POC below shows an example of providing an unvalidated array as a version: https://gist.github.com/jnovikov/184afb593d9c2114d77f508e0ccd508e ### Impact CRLF injection leading to Request Smuggling. ### Workaround If these specific conditions a...

### Summary Improper validation makes it possible for an attacker to modify the HTTP request (e.g. insert a new header) or even create a new HTTP request if the attacker controls the HTTP method. ### Details The vulnerability occurs only if the attacker can control the HTTP method (GET, POST etc.) of the request. Previous releases performed no validation on the provided value. If an attacker controls the HTTP method it will be used as is and can lead to HTTP request smuggling. ### PoC A minimal example can be found here: https://gist.github.com/jnovikov/7f411ae9fe6a9a7804cf162a3bdbb44b ### Impact If the attacker can control the HTTP version of the request it will be able to modify the request (request smuggling). ### Workaround If unable to upgrade and using user-provided values for the request method, perform manual validation of the user value (e.g. by restricting it to a few known values like GET, POST etc.).

# Summary The HTTP parser in AIOHTTP has numerous problems with header parsing, which could lead to request smuggling. This parser is only used when `AIOHTTP_NO_EXTENSIONS` is enabled (or not using a prebuilt wheel). # Details ## Bug 1: Bad parsing of `Content-Length` values ### Description RFC 9110 says this: > `Content-Length = 1*DIGIT` AIOHTTP does not enforce this rule, presumably because of an incorrect usage of the builtin `int` constructor. Because the `int` constructor accepts `+` and `-` prefixes, and digit-separating underscores, using `int` to parse CL values leads AIOHTTP to significant misinterpretation. ### Examples ``` GET / HTTP/1.1\r\n Content-Length: -0\r\n \r\n X ``` ``` GET / HTTP/1.1\r\n Content-Length: +0_1\r\n \r\n X ``` ### Suggested action Verify that a `Content-Length` value consists only of ASCII digits before parsing, as the standard requires. ## Bug 2: Improper handling of NUL, CR, and LF in header values ### Description RFC 9110 says this: > Field ...

aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. The HTTP parser in AIOHTTP has numerous problems with header parsing, which could lead to request smuggling. This parser is only used when AIOHTTP_NO_EXTENSIONS is enabled (or not using a prebuilt wheel). These bugs have been addressed in commit `d5c12ba89` which has been included in release version 3.8.6. Users are advised to upgrade. There are no known workarounds for these issues.

An issue was discovered in Pillow before 10.0.0. It is a Denial of Service that uncontrollably allocates memory to process a given task, potentially causing a service to crash by having it run out of memory. This occurs for truetype in ImageFont when textlength in an ImageDraw instance operates on a long text argument.
