Descriptions

Vim is an open source command line text editor. When parsing relative ex addresses one may unintentionally cause an
overflow. Ironically this happens in the existing overflow check, because the line number becomes negative and LONG_MAX - lnum will cause the overflow. Impact is low, user interaction is required and a crash may not even happen in all situations. This issue has been addressed in commit `060623e` which has been included in release version 9.0.2110. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Vim es un editor de texto de línea de comandos de código abierto. Al analizar direcciones ex relativas, se puede provocar involuntariamente un desbordamiento. Irónicamente, esto sucede en la verificación de desbordamiento existente, porque el número de línea se vuelve negativo y LONG_MAX - lnum provocará el desbordamiento. El impacto es bajo, se requiere la interacción del usuario y es posible que ni siquiera ocurra una falla en todas las situaciones. Este problema se solucionó en el commit `060623e` que se incluyó en la versión 9.0.2110. Se recomienda a los usuarios que actualicen. No se conocen workarounds para esta vulnerabilidad.
