Name of the Vulnerable Software and Affected Versions Text::LineFold versions prior to 2019.002

Description Text::LineFold splits input strings into segments using specific line break characters, such as Vertical Tab (VT) and Form Feed (FF). However, the break function is applied to the entire string instead of individual segments, causing the full input to be duplicated for every segment identified. This behavior can result in excessive resource consumption and a potential denial of service.

Recommendations Update to a version later than 2019.001.
