Description
This security bulletin contains information about 2 vulnerabilities.
1) Use-after-free (CVE-ID: CVE-2022-2889)
CWE-ID: CWE-416 - Use After Free
CVSSv4: 8.4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error within the find_var_also_in_script() function in evalvars.c. A remote attacker can trick the victim to open a specially crafted file, trigger a use-after-free error and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
2) OS Command Injection (CVE-ID: CVE-2026-46483)
CWE-ID: CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
CVSSv4: 1.8 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to execute arbitrary shell commands.
The vulnerability exists due to improper neutralization of special elements in tar#Vimuntar() in runtime/autoload/tar.vim when decompressing .tgz archives via :Vimuntar on Unix-like systems. A remote attacker can supply a crafted archive filename to execute arbitrary shell commands.
User interaction is required to open the crafted file and invoke the non-routine :Vimuntar command, and only Unix-like systems with the tar plugin enabled are vulnerable.
