Descriptions

Algorithmic complexity vulnerability in the sorting algorithms in bzip2 compressing stream (BZip2CompressorOutputStream) in Apache Commons Compress before 1.4.1 allows remote attackers to cause a denial of service (CPU consumption) via a file with many repeating inputs.

Vulnerabilidad de complejidad algorítmica en los algoritmos de ordenamiento de compresión de "stream" bzip2 (BZip2CompressorOutputStream) de Apache Commons Compress anteriores a 1.4.1. Permite a atacantes remotos provocar una denegación de servicio (consumo de la CPU) a través de un archivo con muchas entradas repetidas.

Apache Commons Compress versions 1.0 through 1.4 and Apache Ant versions 1.5 through 1.8.3 suffer from a denial of service vulnerability. The bzip2 compressing streams in Apache Commons Compress and Apache Ant internally use sorting algorithms with unacceptable worst-case performance on very repetitive inputs. A specially crafted input to Compress' BZip2CompressorOutputStream or Ant'stask can be used to make the process spend a very long time while using up all available processing time effectively leading to a denial of service.
