GHSA-4xqq-73wg-5mjp: git-url-parse Regular Expression Denial of Service

giturlparse (aka git-url-parse) through 1.2.2, as used in Semgrep through 1.21.0, is vulnerable to ReDoS (Regular Expression Denial of Service) if parsing untrusted URLs. This might be relevant if Semgrep is analyzing an untrusted package (for example, to check whether it accesses any Git repository at an http:// URL), and that package's author placed a ReDoS attack payload in a URL used by the package.

GHSA-g8ph-74m6-8m7r: ClickHouse vulnerable to client certificate password exposure in client exception

### Summary As initially reported in issue #1331, when client certificate authentication is enabled with password protection, the password (referred to as the client option `sslkey`) may be exposed in client exceptions (e.g., ClickHouseException or SQLException). This vulnerability can potentially lead to unauthorized access, data breaches, and violations of user privacy. ### Details During the handling of ClickHouseException, the client certificate password may be inadvertently exposed when sslkey is specified. This issue can arise when an exception is thrown during the execution of a query or a database operation. The client certificate password is then included in the exception message, which could be logged or exposed to unauthorized parties. ### Impact This vulnerability enables an attacker with access to client exception error messages or logs to obtain client certificate passwords, potentially allowing unauthorized access to sensitive information, data manipulation, and denial...

CVE-2023-25927: IBM Security Verify Access denial of service CVE-2023-25927 Vulnerability Report

IBM Security Verify Access 10.0.0, 10.0.1, 10.0.2, 10.0.3, 10.0.4, and 10.0.5 could allow an attacker to crash the webseald process using specially crafted HTTP requests resulting in loss of access to the system. IBM X-Force ID: 247635.

GHSA-hqxw-f8mx-cpmw: distribution catalog API endpoint can lead to OOM via malicious user input

### Impact Systems that run `distribution` built after a specific commit running on memory-restricted environments can suffer from denial of service by a crafted malicious `/v2/_catalog` API endpoint request. ### Patches Upgrade to at least 2.8.2-beta.1 if you are running `v2.8.x` release. If you use the code from the main branch, update at least to the commit after [f55a6552b006a381d9167e328808565dd2bf77dc](https://github.com/distribution/distribution/commit/f55a6552b006a381d9167e328808565dd2bf77dc). ### Workarounds There is no way to work around this issue without patching. Restrict access to the affected API endpoint: see the recommendations section. ### References `/v2/_catalog` endpoint accepts a parameter to control the maximum amount of records returned (query string: `n`). When not given the default `n=100` is used. The server trusts that `n` has an acceptable value, however when using a maliciously large value, it allocates an array/slice of `n` of strings before fi...

Ubuntu Security Notice USN-6072-1

Ubuntu Security Notice 6072-1 - It was discovered that the Traffic-Control Index implementation in the Linux kernel did not properly perform filter deactivation in some situations. A local attacker could possibly use this to gain elevated privileges. Please note that with the fix for this CVE, kernel support for the TCINDEX classifier has been removed. Lin Ma discovered a race condition in the io_uring subsystem in the Linux kernel, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service.
