TencentOS Server 3: vim (TSSA-2025:0778)

medium Nessus Plugin ID 270642

Synopsis

The remote TencentOS Server 3 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2025:0778 advisory.

 Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

 CVE-2025-53905:
 Vim is an open source, command line text editor. Prior to version 9.1.1552, a path traversal issue in Vims tar.vim plugin can allow overwriting of arbitrary files when opening specially crafted tar archives. Impact is low because this exploit requires direct user interaction. However, successfully exploitation can lead to overwriting sensitive files or placing executable code in privileged locations, depending on the permissions of the process editing the archive. The victim must edit such a file using Vim which will reveal the filename and the file content, a careful user may suspect some strange things going on. Successful exploitation could results in the ability to execute arbitrary commands on the underlying operating system. Version 9.1.1552 contains a patch for the vulnerability.

 CVE-2025-53906:
 Vim is an open source, command line text editor. Prior to version 9.1.1551, a path traversal issue in Vims zip.vim plugin can allow overwriting of arbitrary files when opening specially crafted zip archives.
