Description Murray McAllister 2014-11-13 04:27:33 UTC

It was reported that Wireshark's NCP dissector could crash. It may be possible to make Wireshark crash by injecting a malformed packet onto the wire or by convincing someone to read a malformed packet trace file.

This is reported to affect Wireshark versions 1.12.0 to 1.12.1, and 1.10.0 to 1.10.10. It is fixed in versions 1.12.2 and 1.10.11.

Analysis
========

CVE-2014-8712

In the code of Wireshark's NCP dissector the uninitialized value of buffer[0] in function build_expert_data causes crash.

CVE-2014-8713

In the code of Wireshark's NCP dissector at the line

uni_to_string(get_finfo_value_string(PTREE_FINFO(tree_pointer)), get_finfo_length(PTREE_FINFO(tree_pointer)), buffer);

size of buffer is not verified as returned by the function get_finfo_length(PTREE_FINFO(tree_pointer) before writing into buffer, in case where values get_finfo_length() is large would cause buffer overflow.
