The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-7028-2 advisory.

    It was discovered that the JFS file system contained an out-of-bounds read vulnerability when printing     xattr debug information. A local attacker could use this to cause a denial of service (system crash).

    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:

    - GPU drivers;

    - Greybus drivers;

    - Modular ISDN driver;

    - Multiple devices driver;

    - Network drivers;

    - SCSI drivers;

    - VFIO drivers;

    - F2FS file system;

    - GFS2 file system;

    - JFS file system;

    - NILFS2 file system;

    - Kernel debugger infrastructure;

    - Bluetooth subsystem;

    - IPv4 networking;

    - L2TP protocol;

    - Netfilter;

    - RxRPC session sockets; (CVE-2024-42154, CVE-2023-52527, CVE-2024-26733, CVE-2024-42160, CVE-2021-47188,     CVE-2024-38570, CVE-2024-26851, CVE-2024-26984, CVE-2024-26677, CVE-2024-39480, CVE-2024-27398,     CVE-2022-48791, CVE-2024-42224, CVE-2024-38583, CVE-2024-40902, CVE-2023-52809, CVE-2024-39495,     CVE-2024-26651, CVE-2024-26880, CVE-2024-42228, CVE-2024-27437, CVE-2022-48863)

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.

The remote NewStart CGSL host, running version MAIN 7.02, has kernel packages installed that are affected by multiple vulnerabilities:

  - In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix racy issue from session     lookup and expire Increment the session reference count within the lock for lookup to avoid racy issue     with session expire. (CVE-2024-58087)

  - In the Linux kernel, the following vulnerability has been resolved: nouveau: fix instmem race condition     around ptr stores Running a lot of VK CTS in parallel against nouveau, once every few hours you might see     something like this crash.

Every so often pt->memory->ptrs is NULL. This     ptrs ptr is set in the nv50_instobj_acquire called from nvkm_kmap. If Thread A and Thread B both get to     nv50_instobj_acquire around the same time, and Thread A hits the refcount_set line, and in lockstep thread     B succeeds at refcount_inc_not_zero, there is a chance the ptrs value won't have been stored since     refcount_set is unordered. Force a memory barrier here, I picked smp_mb, since we want it on all CPUs and     it's write followed by a read. v2: use paired smp_rmb/smp_wmb. (CVE-2024-26984)

  - In the Linux kernel, the following vulnerability has been resolved: Bluetooth: Fix use-after-free bugs     caused by sco_sock_timeout When the sco connection is established and then, the sco socket is releasing,     timeout_work will be scheduled to judge whether the sco disconnection is timeout. The sock will be     deallocated later, but it is dereferenced again in sco_sock_timeout. As a result, the use-after-free bugs     will happen.

  - In the Linux kernel, the following vulnerability has been resolved: firewire: nosy: ensure user_length is     taken into account when fetching packet contents Ensure that packet_buffer_get respects the user_length     provided. If the length of the head packet exceeds the user_length, packet_buffer_get will now return 0 to     signify to the user that no data were read and a larger buffer size is required. Helps prevent user space     overflows. (CVE-2024-27401)

  - In the Linux kernel, the following vulnerability has been resolved: riscv: process: Fix kernel gp leakage     childregs represents the registers which are active for the new thread in user context. For a kernel     thread, childregs->gp is never used since the kernel gp is not touched by switch_to. For a user mode     helper, the gp value can be observed in user space after execve or possibly by other means. [From the     email thread] The /* Kernel thread */ comment is somewhat inaccurate in that it is also used for     user_mode_helper threads, which exec a user process, e.g. /sbin/init or when /proc/sys/kernel/core_pattern     is a pipe. Such threads do not have PF_KTHREAD set and are valid targets for ptrace etc. even before they     exec. childregs is the *user* context during syscall execution and it is observable from userspace in at     least five ways: 1. kernel_execve does not currently clear integer registers, so the starting register     state for PID 1 and other user processes started by the kernel has sp = user stack, gp = kernel
    __global_pointer$, all other integer registers zeroed by the memset in the patch comment. This is a bug in     its own right, but I'm unwilling to bet that it is the only way to exploit the issue addressed by this     patch. 2. ptrace(PTRACE_GETREGSET): you can PTRACE_ATTACH to a user_mode_helper thread before it execs,     but ptrace requires SIGSTOP to be delivered which can only happen at user/kernel boundaries. 3.
    /proc/*/task/*/syscall: this is perfectly happy to read pt_regs for user_mode_helpers before the exec     completes, but gp is not one of the registers it returns. 4. PERF_SAMPLE_REGS_USER: LOCKDOWN_PERF normally     prevents access to kernel addresses via PERF_SAMPLE_REGS_INTR, but due to this bug kernel addresses are     also exposed via PERF_SAMPLE_REGS_USER which is permitted under LOCKDOWN_PERF. I have not attempted to     write exploit code. 5. Much of the tracing infrastructure allows access to user registers. I have not     attempted to determine which forms of tracing allow access to user registers without already allowing     access to kernel registers. (CVE-2024-35871)
