#buffer_overflow

View CSAF 1. EXECUTIVE SUMMARY CVSS v3 7.8 ATTENTION: Low attack complexity Vendor: Ashlar-Vellum Equipment: Cobalt, Graphite, Xenon, Argon, Lithium, and Cobalt Share Vulnerabilities: Out-of-Bounds Write, Heap-based Buffer Overflow, Out-of-Bounds Read 2. RISK EVALUATION Successful exploitation of these vulnerabilities could allow an attacker to execute arbitrary code. 3. TECHNICAL DETAILS 3.1 AFFECTED PRODUCTS The following Ashlar-Vellum products are affected: Cobalt: v12 SP0 Build (1204.77) and prior Graphite: v13.0.48 and prior Xenon: v12 SP0 Build (1204.77) and prior Argon: v12 SP0 Build (1204.77) and prior Lithium: v12 SP0 Build (1204.77) and prior 3.2 Vulnerability Overview 3.2.1 OUT-OF-BOUNDS WRITE CWE-787 In Ashlar-Vellum Cobalt, Xenon, Argon, Lithium, and Cobalt Share v12 SP0 Build (1204.77), the affected applications lack proper validation of user-supplied data when parsing XE files. This could lead to an out-of-bounds write. An attacker could leverage this vulnerability to ex...

Potential buffer overflow vulnerability at the following location in the Zephyr STM32 Crypto driver

Potential buffer overflows in the Bluetooth subsystem due to asserts being disabled in /subsys/bluetooth/host/hci_core.c

A heap-based Buffer Overflow flaw was discovered in Samba. It could allow a remote, authenticated attacker to exploit this vulnerability to cause a denial of service.

Attackers could exploit these vulnerabilities in the SoftEther VPN solution for individual and enterprise users to force users to drop their connections or execute arbitrary code on the targeted machine.

Virtualization services provider VMware has alerted customers to the existence of a proof-of-concept (PoC) exploit for a recently patched security flaw in Aria Operations for Logs. Tracked as CVE-2023-34051 (CVSS score: 8.1), the high-severity vulnerability relates to a case of authentication bypass that could lead to remote code execution. "An unauthenticated, malicious actor can inject files

Ubuntu Security Notice 6445-2 - It was discovered that the IPv6 implementation in the Linux kernel contained a high rate of hash collisions in connection lookup table. A remote attacker could use this to cause a denial of service. Daniel Trujillo, Johannes Wikner, and Kaveh Razavi discovered that some AMD processors utilising speculative execution and branch prediction may allow unauthorised memory reads via a speculative side-channel attack. A local attacker could use this to expose sensitive information, including kernel memory.

Ubuntu Security Notice 6446-2 - Ross Lagerwall discovered that the Xen netback backend driver in the Linux kernel did not properly handle certain unusual packets from a paravirtualized network frontend, leading to a buffer overflow. An attacker in a guest VM could use this to cause a denial of service or possibly execute arbitrary code. Bien Pham discovered that the netfiler subsystem in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. A local user could use this to cause a denial of service or possibly execute arbitrary code.

Kyle Zeng discovered that the networking stack implementation in the Linux kernel did not properly validate skb object size in certain conditions. An attacker could use this cause a denial of service or possibly execute arbitrary code.
