Descriptions

In Wireshark 2.4.0 to 2.4.5 and 2.2.0 to 2.2.13, the NBAP dissector could crash with a large loop that ends with a heap-based buffer overflow. This was addressed in epan/dissectors/packet-nbap.c by prohibiting the self-linking of DCH-IDs.

En Wireshark 2.4.0 a 2.4.5 y 2.2.0 a 2.2.13, el disector NBAP podría cerrarse inesperadamente con un gran bucle que termina con un desbordamiento de búfer basado en memoria dinámica (heap). Esto se trató en epan/dissectors/packet-nbap.c c prohibiendo el autoenlazado de DCH-ID.

It was discovered that Wireshark, a network protocol analyzer, contained several vulnerabilities in the dissectors for PCP, ADB, NBAP, UMTS MAC, IEEE 802.11, SIGCOMP, LDSS, GSM A DTAP and Q.931, which result in denial of service or the execution of arbitrary code.
