Description Srikanth Balasubramanian 2026-08-27 10:08:05 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

Non-progress DoS in EUC_JISX0213 -&gt; UCS-4 conversion state  <br/>
handling (`iconvdata/euc_jisx0213.c`): crafted input can cause repeated  <br/>
emission of a buffered code point without further input consumption,  <br/>
leading to persistent retry churn and denial of service in callers  <br/>
converting untrusted text.<br/>
