Deserialization of Untrusted Data vulnerability in Apache Software Foundation Apache Johnzon. A malicious attacker can craft up some JSON input that uses large numbers (numbers such as 1e20000000) that Apache Johnzon will deserialize into BigDecimal and maybe use numbers too large which may result in a slow conversion (Denial of service risk). Apache Johnzon 1.2.21 mitigates this by setting a scale limit of 1000 (by default) to the BigDecimal. This issue affects Apache Johnzon: through 1.2.20.
Google has released its monthly security updates for the Android operating system, addressing 46 new software vulnerabilities. Among these, three vulnerabilities have been identified as actively exploited in targeted attacks. One of the vulnerabilities tracked as CVE-2023-26083 is a memory leak flaw affecting the Arm Mali GPU driver for Bifrost, Avalon, and Valhall chips. This particular
Ubuntu Security Notice 6206-1 - Hangyu Hua discovered that the Flower classifier implementation in the Linux kernel contained an out-of-bounds write vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the NTFS file system implementation in the Linux kernel contained a null pointer dereference in some situations. A local attacker could use this to cause a denial of service.
Ubuntu Security Notice 6207-1 - It was discovered that the TUN/TAP driver in the Linux kernel did not properly initialize socket data. A local attacker could use this to cause a denial of service. It was discovered that the Real-Time Scheduling Class implementation in the Linux kernel contained a type confusion vulnerability in some situations. A local attacker could use this to cause a denial of service.
Ubuntu Security Notice 6205-1 - Hangyu Hua discovered that the Flower classifier implementation in the Linux kernel contained an out-of-bounds write vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that for some Intel processors the INVLPG instruction implementation did not properly flush global TLB entries when PCIDs are enabled. An attacker could use this to expose sensitive information or possibly cause undesired behaviors.
The fix for CVE-2023-24998 was incomplete. If non-default HTTP connector settings were used such that the maxParameterCount could be reached using query string parameters and a request was submitted that supplied exactly maxParameterCount parameters in the query string, the limit for uploaded request parts could be bypassed with the potential for a denial of service to occur.
is.js is a general-purpose check library. Versions 0.9.0 and prior contain one or more regular expressions that are vulnerable to Regular Expression Denial of Service (ReDoS). is.js uses a regex copy-pasted from a gist to validate URLs. Trying to validate a malicious string can cause the regex to loop "forever." This vulnerability was found using a CodeQL query which identifies inefficient regular expressions. is.js has no patch for this issue.
The economic damage of DDoS attacks is tough to measure — who can really say how much money Blizzard missed out on by not having players in “Diablo IV” for a few hours spending money on microtransactions or choosing to buy the game?
In all, Cisco Talos is releasing 22 security advisories today, nine of which have a CVSS score greater than 8, associated with 69 CVEs.
An access violation vulnerability exists in the eventcore functionality of Milesight UR32L v32.3.0.5. A specially crafted network request can lead to denial of service. An attacker can send a network request to trigger this vulnerability.
