CVE-ID : CVE-2020-28374
Package : linux-zen
Type : directory traversal
Remote : No
Link : https://security.archlinux.org/AVG-1444
The package linux-zen before version 5.10.7.zen1-1 is vulnerable to
directory traversal.
Upgrade to 5.10.7.zen1-1.
The problem has been fixed upstream in version 5.10.7.zen1.
None.
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.
An attacker can traverse directories on the system through malicious
operations.
