CVE-2025-14549

In the Eclipse OMR compiler component, since release 0.7.0, an optimization enabled for Eclipse OpenJ9 consumers of OMR on Z processors incorrectly handles NUL (0x00) characters during the Latin-compatible charset (UTF-8, ISO8859-1, ASCII, etc) to IBM-1047/037 translation sequence. This can cause the output byte array to be truncated, discarding the first NUL byte and all subsequent characters, and thereby exposing a possible buffer over-read problem. This issue is fixed in Eclipse OMR version 0.8.0.

Summary		(es) En el componente compilador Eclipse OMR, desde la versión 0.7.0, una optimización habilitada para los consumidores de OMR de Eclipse OpenJ9 en procesadores Z maneja incorrectamente los caracteres NUL (0x00) durante la secuencia de traducción de conjuntos de caracteres compatibles con Latin (UTF-8, ISO8859-1, ASCII, etc.) a IBM-1047/037. Esto puede causar que el array de bytes de salida se trunque, descartando el primer byte NUL y todos los caracteres subsiguientes, y exponiendo así un posible problema de lectura excesiva de búfer. Este problema está solucionado en la versión 0.8.0 de Eclipse OMR.
