Language:
Synopsis
The remote SUSE host is missing one or more security updates.Description
The remote SUSE Linux SLES12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:4359-1 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.
