Background
mime-support is a utility package in the Debian ecosystem that provides support for handling MIME types and mailcap files. It includes the run-mailcap utility, which allows the execution of programs based on entries in the mailcap file. This package is vulnerable to a shell command injection attack, where an attacker can exploit shell meta-characters in filenames to execute arbitrary code remotely.
Vulnerability Detail
The vulnerability in mime-support arises from the lack of proper input validation in the run-mailcap utility. By crafting a malicious filename with shell meta-characters, an attacker can inject arbitrary shell commands that will be executed when the file is processed by run-mailcap. This can lead to remote code execution, allowing the attacker to execute arbitrary commands on the target system with the privileges of the user running run-mailcap.
How To Fix

Workaround
There is no specific workaround mentioned for this vulnerability. However, as a general best practice, it is recommended to exercise caution when processing files with potentially untrusted filenames. Avoid using filenames that contain shell meta-characters and ensure proper input validation and sanitization to prevent command injection attacks.
Conclusion
The vulnerability in mime-support allows for remote code execution through shell command injection. To mitigate this vulnerability, it is crucial to upgrade the mime-support package to version 3.52-1+deb7u1 or later. Exercise caution when processing files with potentially untrusted filenames and ensure proper input validation to prevent command injection attacks.
