### Summary The [patch that addressed CVE-2023-40581](https://github.com/yt-dlp/yt-dlp/commit/de015e930747165dbb8fcd360f8775fd973b7d6e) attempted to prevent RCE when using `--exec` with `%q` by replacing double quotes with two double quotes. However, this escaping is not sufficient, and still allows expansion of environment variables. Support for output template expansion in `--exec`, along with this vulnerable behavior, was added to `yt-dlp` in version [2021.04.11](https://github.com/yt-dlp/yt-dlp/releases/tag/2021.04.11). ```cmd > yt-dlp "https://youtu.be/42xO6rVqf2E" --ignore-config -f 18 --exec "echo %(title)q" [youtube] Extracting URL: https://youtu.be/42xO6rVqf2E [youtube] 42xO6rVqf2E: Downloading webpage [youtube] 42xO6rVqf2E: Downloading ios player API JSON [youtube] 42xO6rVqf2E: Downloading android player API JSON [youtube] 42xO6rVqf2E: Downloading m3u8 information [info] 42xO6rVqf2E: Downloading 1 format(s): 18 [download] Destination: %CMDCMDLINE:~-1%&echo pwned&calc.exe [4...
On April 9, Twitter/X began automatically modifying links that mention "twitter.com" to redirect to "x.com" instead. But over the past 48 hours, dozens of new domain names have been registered that demonstrate how this change could be used to craft convincing phishing links -- such as fedetwitter[.]com, which is currently rendered as fedex.com in tweets.
A critical security flaw in the Rust standard library could be exploited to target Windows users and stage command injection attacks. The vulnerability, tracked as CVE-2024-24576, has a CVSS score of 10.0, indicating maximum severity. That said, it only impacts scenarios where batch files are invoked on Windows with untrusted arguments. "The Rust standard library did not properly escape
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
The US Congress will this week decide the fate of Section 702, a major surveillance program that will soon expire if lawmakers do not act. WIRED is tracking the major developments as they unfold.
### Summary The vulnerability impacts only users of the `IdTokenVerifier` class. The verify method in `IdTokenVerifier` does not validate the signature before verifying the claims (e.g., iss, aud, etc.). Signature verification makes sure that the token's payload comes from valid provider, not from someone else. An attacker can provide a compromised token with modified payload like email or phone number. The token will pass the validation by the library. Once verified, modified payload can be used by the application. If the application sends verified `IdToken` to other service as is like for auth - the risk is low, because the backend of the service is expected to check the signature and fail the request. Reporter: [Tamjid al Rahat](https://github.com/tamjidrahat), contributor ### Patches The issue was fixed in the 1.33.3 version of the library ### Proof of Concept To reproduce, one needs to call the verify function with an IdToken instance that contains a malformed signature to ...
It was discovered that a race condition existed in the io_uring subsystem in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. Lonial Con discovered that the netfilter subsystem in the Linux kernel contained a memory leak when handling certain element flush operations. A local attacker could use this to expose sensitive information (kernel memory). Various other issues were also addressed.
Ubuntu Security Notice 6701-4 - Ruihan Li discovered that the bluetooth subsystem in the Linux kernel did not properly perform permissions checks when handling HCI sockets. A physically proximate attacker could use this to cause a denial of service. It was discovered that the NVIDIA Tegra XUSB pad controller driver in the Linux kernel did not properly handle return values in certain error conditions. A local attacker could use this to cause a denial of service.
Ubuntu Security Notice 6726-1 - Pratyush Yadav discovered that the Xen network backend implementation in the Linux kernel did not properly handle zero length data request, leading to a null pointer dereference vulnerability. An attacker in a guest VM could possibly use this to cause a denial of service. It was discovered that the IPv6 implementation of the Linux kernel did not properly manage route cache memory usage. A remote attacker could use this to cause a denial of service.
Ubuntu Security Notice 6725-1 - Chih-Yen Chang discovered that the KSMBD implementation in the Linux kernel did not properly validate certain data structure fields when parsing lease contexts, leading to an out-of-bounds read vulnerability. A remote attacker could use this to cause a denial of service or possibly expose sensitive information. Quentin Minster discovered that a race condition existed in the KSMBD implementation in the Linux kernel, leading to a use-after-free vulnerability. A remote attacker could use this to cause a denial of service or possibly execute arbitrary code.
