GHSA-7C3F-H49G-4MG6
Vulnerability from github – Published: 2022-05-24 17:33 – Updated: 2022-05-24 17:33A vulnerability in Cisco Unified Communications Manager IM & Presence Service (Unified CM IM&P) Software could allow an authenticated, remote attacker to cause the Cisco XCP Authentication Service on an affected device to restart, resulting in a denial of service (DoS) condition. The vulnerability is due to improper handling of login requests. An attacker could exploit this vulnerability by sending a crafted client login request to an affected device. A successful exploit could allow the attacker to cause a process to crash, resulting in a DoS condition for new login attempts. Users who are authenticated at the time of the attack would not be affected. There are workarounds that address this vulnerability.

GHSA-7C4J-2M43-2MGH
Vulnerability from github – Published: 2026-04-22 19:19 – Updated: 2026-04-27 16:22Impact
An untrusted p2p peer can cause a node to panic by announcing an election macro block whose validators set contains an invalid compressed BLS voting key.
Hashing an election macro header hashes validators and reaches Validators::voting_keys(), which calls validator.voting_key.uncompress().unwrap() and panics on invalid bytes.
Patches
The patch for this vulnerability is included as part of v1.3.0.
Workarounds
No known workarounds.

GHSA-7HWJ-X2VH-JQV9
Vulnerability from github – Published: 2024-11-19 18:31 – Updated: 2025-11-04 00:32In the Linux kernel, the following vulnerability has been resolved:
media: dvbdev: prevent the risk of out of memory access
The dvbdev contains a static variable used to store dvb minors.
The behavior of it depends if CONFIG_DVB_DYNAMIC_MINORS is set or not. When not set, dvb_register_device() won't check for boundaries, as it will rely that a previous call to dvb_register_adapter() would already be enforcing it.
On a similar way, dvb_device_open() uses the assumption that the register functions already did the needed checks.
This can be fragile if some device ends using different calls. This also generate warnings on static check analysers like Coverity.
So, add explicit guards to prevent potential risk of OOM issues.

Vulnerability from github – Published: 2021-05-24 16:57 – Updated: 2023-02-14 00:21Impact
The TokenRevocationHandler ignores errors coming from the storage. This can lead to unexpected 200 status codes indicating successful revocation while the token is still valid. Whether an attacker can use this for her advantage depends on the ability to trigger errors in the store.
References
RFC 7009 states that a 503 HTTP code must be returned when the server has a problem.

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.

"details": "Multiple 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.",
