Name of the Vulnerable Software and Affected Versions xterm versions prior to 380

Description The issue is related to the ReGIS reporting feature in xterm, which can lead to a pointer/overflow problem when handling character-set names with unexpected characters. This can occur in xterm installations configured to use a certain experimental feature at compile time. The vulnerability may allow a remote attacker to impact the confidentiality, integrity, and availability of protected information.

Recommendations For xterm versions prior to 380, update to version 380 or later to resolve the issue. As a temporary workaround, consider disabling the ReGIS reporting feature until a patch is available. Restrict access to the experimental feature configured at compile time to minimize the risk of exploitation.
