Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6767-2 advisory.

 Chenyuan Yang discovered that the RDS Protocol implementation in the Linux kernel contained an out-of- bounds read vulnerability. An attacker could use this to possibly cause a denial of service (system crash). (CVE-2024-23849)

 Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems:

 - ARM64 architecture;

 - PowerPC architecture;

 - S390 architecture;

 - Block layer subsystem;

 - Android drivers;

 - Hardware random number generator core;

 - GPU drivers;

 - Hardware monitoring drivers;

 - I2C subsystem;

 - IIO Magnetometer sensors drivers;

 - InfiniBand drivers;

 - Network drivers;

 - PCI driver for MicroSemi Switchtec;

 - PHY drivers;

 - Ceph distributed file system;

 - Ext4 file system;

 - JFS file system;

 - NILFS2 file system;

 - Pstore file system;

 - Core kernel;

 - Memory management;

 - CAN network layer;

 - Networking core;

 - IPv4 networking;

 - Logical Link layer;

 - Netfilter;

 - NFC subsystem;

 - SMC sockets;

 - Sun RPC protocol;

 - TIPC protocol;

 - Realtek audio codecs; (CVE-2024-26696, CVE-2023-52583, CVE-2024-26720, CVE-2023-52615, CVE-2023-52599, CVE-2023-52587, CVE-2024-26635, CVE-2024-26704, CVE-2024-26625, CVE-2024-26825, CVE-2023-52622, CVE-2023-52435, CVE-2023-52617, CVE-2023-52598, CVE-2024-26645, CVE-2023-52619, CVE-2024-26593, CVE-2024-26685, CVE-2023-52602, CVE-2023-52486, CVE-2024-26697, CVE-2024-26675, CVE-2024-26600, CVE-2023-52604, CVE-2024-26664, CVE-2024-26606, CVE-2023-52594, CVE-2024-26671, CVE-2024-26598, CVE-2024-26673, CVE-2024-26920, CVE-2024-26722, CVE-2023-52601, CVE-2024-26602, CVE-2023-52637, CVE-2023-52623, CVE-2024-26702, CVE-2023-52597, CVE-2024-26684, CVE-2023-52606, CVE-2024-26679, CVE-2024-26663, CVE-2024-26910, CVE-2024-26615, CVE-2023-52595, CVE-2023-52607, CVE-2024-26636)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
