CVE-ID: CVE-2021-44832
CWE-ID:
CWE-94 - Improper Control of Generation of Code ('Code Injection')
Exploit availability: No
DescriptionThe 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.
MitigationInstall updates from vendor's website.

2) Input validation error
EUVDB-ID: #VU22598
Risk: Low
CVSSv3.1: 2.5 [CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-14866
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to GNU cpio does not properly validate files when writing tar headers during tar archive creation. A local user can trick the victim into creating a tar archive out of a directory with specially crafted files. As a result the generated archive may contain files that the attacker does not have access to.

3) Improper Resource Shutdown or Release
EUVDB-ID: #VU59473
Risk: Low
CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-36322
CWE-ID:
CWE-404 - Improper Resource Shutdown or Release
Exploit availability: No
DescriptionThe 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).
