CVE-2022-0019 2 Linux, Paloaltonetworks 2 Linux Kernel, Globalprotect 2024-11-21 1.9 LOW 4.7 MEDIUM
An insufficiently protected credentials vulnerability exists in the Palo Alto Networks GlobalProtect app on Linux that exposes the hashed credentials of GlobalProtect users that saved their password during previous GlobalProtect app sessions to other local users on the system. The exposed credentials enable a local attacker to authenticate to the GlobalProtect portal or gateway as the target user without knowing of the target user’s plaintext password. This issue impacts: GlobalProtect app 5.1 versions earlier than GlobalProtect app 5.1.10 on Linux. GlobalProtect app 5.2 versions earlier than and including GlobalProtect app 5.2.7 on Linux. GlobalProtect app 5.3 versions earlier than GlobalProtect app 5.3.2 on Linux. This issue does not affect the GlobalProtect app on other platforms.
CVE-2021-4439 1 Linux 1 Linux Kernel 2024-11-21 N/A 7.8 HIGH
In the Linux kernel, the following vulnerability has been resolved: isdn: cpai: check ctr->cnr to avoid array index out of bound The cmtp_add_connection() would add a cmtp session to a controller and run a kernel thread to process cmtp. __module_get(THIS_MODULE); session->task = kthread_run(cmtp_session, session, "kcmtpd_ctr_%d", session->num); During this process, the kernel thread would call detach_capi_ctr() to detach a register controller. if the controller was not attached yet, detach_capi_ctr() would trigger an array-index-out-bounds bug.
