GHSA-7RW7-XM59-WMR8
Vulnerability from github – Published: 2022-05-24 17:45 – Updated: 2022-05-24 17:45Multiple vulnerabilities in the web UI of Cisco IOS XE Software could allow an authenticated, remote attacker with read-only privileges to cause the web UI software to become unresponsive and consume vty line instances, resulting in a denial of service (DoS) condition. These vulnerabilities are due to insufficient error handling in the web UI. An attacker could exploit these vulnerabilities by sending crafted HTTP packets to an affected device. A successful exploit could allow the attacker to cause the web UI software to become unresponsive and consume all available vty lines, preventing new session establishment and resulting in a DoS condition. Manual intervention would be required to regain web UI and vty session functionality. Note: These vulnerabilities do not affect the console connection.

GHSA-7VM6-QWH5-9X44
Vulnerability from github – Published: 2024-11-04 23:22 – Updated: 2024-11-05 18:35Summary
loona-hpack suffers from the same vulnerability as the original hpack as documented in https://github.com/mlalic/hpack-rs/issues/11
Details
The original includes a very nice description of the problem, as well as an easy-enough fix for it.
PoC
The original example pretty much still applies:
use loona_hpack::Decoder;
pub fn main() {
let input = &[0x3f];
let mut decoder = Decoder::new();
let _ = decoder.decode(input);
}
Impact
From the original:
All users who try to decode untrusted input using the Decoder are vulnerable to this exploit. A patched version of the crate is available on [crates.io](https://crates.io/crates/hpack-patched) under the name hpack-patched. See [Cargo's documentation on overriding dependencies](https://doc.rust-lang.org/cargo/reference/overriding-dependencies.html) for more information.
