Descriptions

The wmem_block_split_free_chunk function in epan/wmem/wmem_allocator_block.c in the wmem block allocator in the memory manager in Wireshark 1.12.x before 1.12.7 does not properly consider a certain case of multiple realloc operations that restore a memory chunk to its original size, which allows remote attackers to cause a denial of service (incorrect free operation and application crash) via a crafted packet.

Vulnerabilidad en la función wmem_block_split_free_chunk en epan/wmem/wmem_allocator_block.c en el asignador wmem block en el gestor de memoria en Wireshark 1.12.x en versiones anteriores a 1.12.7, no considera adecuadamente un cierto caso de operaciones de reasignación de memoria múltiple que restablecen un fragmento de memoria a su tamaño original, lo que permite a atacantes remotos causar una denegación de servicio (operación de liberación incorrecta y caída de la aplicación) a través de un paquete manipulado.
