[ASA-202101-33] linux: directory traversal
Arch Linux Security Advisory ASA-202101-33 ========================================== Severity: Medium Date : 2021-01-20 CVE-ID : CVE-2020-28374 Package : linux Type : directory traversal Remote : No Link : https://security.archlinux.org/AVG-1442 Summary ======= The package linux before version 5.10.7.arch1-1 is vulnerable to directory traversal. Resolution ========== Upgrade to 5.10.7.arch1-1. # pacman -Syu "linux>=5.10.7.arch1-1" The problem has been fixed upstream in version 5.10.7.arch1. Workaround ========== None. Description =========== 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. Impact ====== An attacker can traverse directories on the system through malicious operations.
