AI-suggested

Currently, no effective mitigation is available that meets Red Hat's criteria for ease of use, deployment, and applicability. Until then, avoid using the interactive shell mode of xmllint with untrusted input. No urgent remediation is required given the low likelihood of exploitation and limited impact.

Description

A vulnerability exists in the interactive shell of the xmllint command-line tool used for parsing XML files in Red Hat Enterprise Linux AI. The flaw involves improper input size checking for overly long commands, which can cause the program to crash. Exploitation requires local access and manual interaction with the tool, making it unlikely in typical environments. The impact is limited to availability due to potential crashes, with no known remote code execution or data compromise.
