Descriptions
In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, dissectors that support zlib decompression could crash. This was addressed in epan/tvbuff_zlib.c by rejecting negative lengths to avoid a buffer over-read.
En Wireshark, de la versión 2.6.0 a la 2.6.1, de la versión 2.4.0 a la 2.4.7 y de la versión 2.2.0 a la 2.2.15, los disectores que soportan la descompresión zlib podrían cerrarse inesperadamente. Esto se abordó en epan/tvbuff_zlib.c rechazando longitudes negativas para evitar una sobrelectura de búfer.
