Fedora 33 : kernel / kernel-headers (2021-620fb40359)

high Nessus Plugin ID 145107

Language:

Synopsis

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

Description

The remote Fedora 33 host has packages installed that are affected by multiple vulnerabilities as referenced in the FEDORA-2021-620fb40359 advisory.

- In drivers/target/target_core_xcopy.c in the Linux kernel before 5.10.7, insufficient identifier checking in the LIO SCSI target code can be used by remote attackers to read or write files via directory traversal in an XCOPY request, aka CID-2896c93811e3. For example, an attack can occur over a network if the attacker has access to one iSCSI LUN. The attacker gains control over file access because I/O operations are proxied via an attacker-selected backstore. (CVE-2020-28374)

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

Solution

Update the affected kernel and / or kernel-headers packages.
