Red Hat Security Advisory 2024-1722-03 - An update for edk2 is now available for Red Hat Enterprise Linux 8.2 Advanced Update Support, Red Hat Enterprise Linux 8.2 Update Services for SAP Solutions, and Red Hat Enterprise Linux 8.2 Telecommunications Update Service. Issues addressed include a buffer overflow vulnerability.

Red Hat uses a four-point impact scale to classify security issues affecting our products. Have you ever asked yourself what it takes and what the requirements are for each point of the scale? We will talk through the highlights of our process in this article.Is this a CVE?First and foremost, what is a CVE? Short for Common Vulnerabilities and Exposures, it is a list of publicly disclosed computer security flaws. Learn more in this Red Hat post.To receive a severity rating, the issue needs to be a CVE. But what does it take to be a CVE? In order to warrant a CVE ID, a vulnerability has to comp

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to take additional actions prior to exploitation to prepare the target environment.

Given the function `transpose::transpose`: ```rust fn transpose<T: Copy>(input: &[T], output: &mut [T], input_width: usize, input_height: usize) ``` The safety check `input_width * input_height == output.len()` can fail due to `input_width * input_height` overflowing in such a way that it equals `output.len()`. As a result of failing the safety check, memory past the end of `output` is written to. This only occurs in release mode since `*` panics on overflow in debug mode. Exploiting this issue requires the caller to pass `input_width` and `input_height` arguments such that multiplying them overflows, and the overflown result equals the lengths of input and output slices.

With versions of the whoami crate >= 0.5.3 and < 1.5.0, calling any of these functions leads to an immediate stack buffer overflow on illumos and Solaris: - `whoami::username` - `whoami::realname` - `whoami::username_os` - `whoami::realname_os` With versions of the whoami crate >= 0.5.3 and < 1.0.1, calling any of the above functions also leads to a stack buffer overflow on these platforms: - Bitrig - DragonFlyBSD - FreeBSD - NetBSD - OpenBSD This occurs because of an incorrect definition of the `passwd` struct on those platforms. As a result of this issue, denial of service and data corruption have both been observed in the wild. The issue is possibly exploitable as well. This vulnerability also affects other Unix platforms that aren't Linux or macOS. This issue has been addressed in whoami 1.5.0.

Google has issued patches for 28 security vulnerabilities, including a critical patch for Androids with Qualcomm chips.

In _imagingcms.c in Pillow before 10.3.0, a buffer overflow exists because strcpy is used instead of strncpy.
