Denial Of Service (DoS)

MessagePack is vulnerable to a Denial Of Service DoS. This vulnerability is due to hash collisions triggered by specially crafted data, which allows an attacker to cause excessive CPU consumption during deserialization of untrusted data. A workaround involves creating a custom hash function by...

GHSA-4GFW-WF7C-W6G2 Authd allows attacker-controlled usernames to yield controllable UIDs

CVE description: Authd, through version 0.3.6, did not sufficiently randomize user IDs to prevent collisions. A local attacker who can register user names could spoof another user's ID and gain their privileges. ----- original report ----- Cause authd assigns user IDs as a pure function of the us...

Amazon Linux 2 : xerces-j2 (ALAS-2024-2649)

The version of xerces-j2 installed on the remote host is prior to 2.11.0-17. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2649 advisory. Apache Xerces2 Java Parser before 2.12.0 allows remote attackers to cause a denial of service CPU consumption via a crafted...

Medium: xerces-j2

Issue Overview: Apache Xerces2 Java Parser before 2.12.0 allows remote attackers to cause a denial of service CPU consumption via a crafted message to an XML service, which triggers hash table collisions. CVE-2012-0881 There's a vulnerability within the Apache Xerces Java XercesJ XML parser when...

The vulnerability of the JSON aeson analysis and encoding library, related to insufficient encryption strength, allows attackers to trigger a service denial.

The vulnerability of the JSONeson analysis and encoding library is related to the creation of a collision in the basic unordered-containers library, by sending specially created JSON data. Exploiting this vulnerability can allow an attacker to cause a service failure remotely...

SUSE-SU-2024:2963-1 Security update for osc

This update for osc fixes the following issues: 0.183.0 - Fix possibility to overwrite special files in .osc CVE-2024-22034 bsc1225911 Source files are now stored in the 'sources' subdirectory which prevents name collisons. This requires changing version of '.osc' store to 2.0. - Fix errorneous...

In the Linux kernel before 5.1.7 a device can be tracked by an attacker using the IP ID values the kernel produces for connection-less protocols (e.g. UDP and ICMP). When such traffic is sent to multiple destination IP addresses it is possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). An attack may be conducted by hosting a crafted web page that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses.
