REDHAT-BUG-2372952: Buffer Overflow

Stack-based buffer overflow vulnerability in the interactive shell of the xmllint tool in libxml2. The issue is caused by an unsafe use of strcpy() when processing user-supplied command-line input. When an attacker passes an overly long argument to any shell command (e.g., exit, cat, etc.), the input exceeds the fixed-size stack buffer, resulting in a crash or potentially arbitrary code execution on systems lacking stack protections. This vulnerability affects only the interactive shell and requires that an attacker can influence or control the command input to xmllint, which is uncommon in typical deployments.
