Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Code Injection (CVE-ID: CVE-2021-44832)
The vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to improper input validation. A remote user with permission to modify the logging configuration file can construct a malicious configuration using a JDBC Appender with a data source referencing a JNDI URI which can execute remote code.
2) Memory leak (CVE-ID: CVE-2020-25704)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to memory leak within the Linux kernel performance monitoring subsystem when using PERF_EVENT_IOC_SET_FILTER. A local user could use this flaw to starve the resources causing denial of service.
3) Improper Resource Shutdown or Release (CVE-ID: CVE-2020-36322)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists in the FUSE filesystem implementation in the Linux kernel due to fuse_do_getattr() calls make_bad_inode() in inappropriate situations. A local user can run a specially crafted program to trigger kernel crash.
Note, the vulnerability exists due to incomplete fix for #VU58207 (CVE-2021-28950).
4) Buffer overflow (CVE-ID: CVE-2021-42739)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary within the firewire subsystem in the Linux kernel in drivers/media/firewire/firedtv-avc.c and drivers/media/firewire/firedtv-ci.c files. A local privileged user can run a specially crafted program tat calls avc_ca_pmt() function to trigger memory corruption and execute arbitrary code with elevated privileges.
