SUSE SLED12 / SLES12 Security Update : kernel (SUSE-SU-2023:4349-1)

medium Nessus Plugin ID 184346

Language:

Synopsis

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

Description

The remote SUSE Linux SLED12 / SLED_SAP12 / SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:4349-1 advisory.

- An issue was discovered in drivers/mtd/ubi/cdev.c in the Linux kernel 6.2. There is a divide-by-zero error in do_div(sz,mtd->erasesize), used indirectly by ctrl_cdev_ioctl, when mtd->erasesize is 0.
(CVE-2023-31085)

- The vulnerability exists due to improper event handling in Linux kernel. A malicious guest can disable paravirtualized device to cause a deadlock in a backend domain (other than dom0). (CVE-2023-34324)

- A flaw was found in the Netfilter subsystem in the Linux kernel. The nfnl_osf_add_callback function did not validate the user mode controlled opt_num field. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read, leading to a crash or information disclosure. (CVE-2023-39189)

- An issue was discovered in drivers/usb/storage/ene_ub6250.c for the ENE UB6250 reader driver in the Linux kernel before 6.2.5. An object could potentially extend beyond the end of an allocation. (CVE-2023-45862)

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

Solution

Update the affected packages.
