Title
Integer underflow leading to stack overflow in FPC codec decompression
Summary
ClickHouse® is an open-source column-oriented database management system that allows generating analytical data reports in real-time. This vulnerability is an integer underflow resulting in crash due to stack buffer overflow in decompression of FPC codec. It can be triggered and exploited by an unauthenticated attacker. The vulnerability is very similar to CVE-2023-47118 with how the vulnerable function can be exploited.

Title
gnark vulnerable to unsoundness in variable comparison/non-unique binary decomposition
Summary
gnark is a zk-SNARK library that offers a high-level API to design circuits. Prior to version 0.9.0, for some in-circuit values, it is possible to construct two valid decomposition to bits. In addition to the canonical decomposition of `a`, for small values there exists a second decomposition for `a+r` (where `r` is the modulus the values are being reduced by). The second decomposition was possible due to overflowing the field where the values are defined. Upgrading to version 0.9.0 should fix the issue without needing to change the calls to value comparison methods.

Title
Exim libspf2 Integer Underflow Remote Code Execution Vulnerability
Summary
Exim libspf2 Integer Underflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Exim libspf2. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the parsing of SPF macros. When parsing SPF macros, the process does not properly validate user-supplied data, which can result in an integer underflow before writing to memory. An attacker can leverage this vulnerability to execute code in the context of the service account.
. Was ZDI-CAN-17578.

Affected versions are subject to an Integer-Underflow leading to Out-Of-Bound Read in the `zgfx_decompress_segment` function. In the context of `CopyMemory`, it's possible to read data beyond the transmitted packet range and likely cause a crash. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3. Users are advised to upgrade. There are no known workarounds for this issue.

Summary
Multiple integer underflow vulnerabilities exist in the LXT2 lxt2_rd_iter_radix shift operation functionality of GTKWave 3.3.115. A specially crafted .lxt2 file can lead to memory corruption. A victim would need to open a malicious file to trigger these vulnerabilities.This vulnerability concerns the integer underflow when performing the right shift operation.

Title
Incorrect offset calculation leading to denial of service in FreeRDP
Summary
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. This issue affects Clients only. Integer underflow leading to DOS (e.g. abort due to `WINPR_ASSERT` with default compilation flags). When an insufficient blockLen is provided, and proper length validation is not performed, an Integer Underflow occurs, leading to a Denial of Service (DOS) vulnerability. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3. Users are advised to upgrade. There are no known workarounds for this vulnerability.
