Other vulnerabilities in Wireshark
See all- CVE-2017-17997High
In Wireshark before version 2.2.12, the MRDISC dissector misuses a NULL pointer, causing the program to crash. This issue was addressed by validating an IPv4 address.
- CVE-2017-17935High
The File_read_line function in Wireshark up to version 2.2.11 does not properly strip ' ' characters, allowing remote attackers to cause application crashes via crafted packets that trigger the processing of an empty line.
- CVE-2017-17083High
In Wireshark versions 2.4.0 to 2.4.2 and 2.2.0 to 2.2.10, the NetBIOS dissector could crash. This was addressed by ensuring that write operations are bounded by the beginning of a buffer.
- CVE-2017-13767High
In Wireshark versions 2.4.0, 2.2.0 to 2.2.8, and 2.0.0 to 2.0.14, the MSDP dissector could go into an infinite loop. This was addressed by adding length validation.
- CVE-2017-11410High
In Wireshark versions up to 2.0.13 and 2.2.x up to 2.2.7, the WBXML dissector could enter an infinite loop triggered by packet injection or a malformed capture file. This was addressed by adding validation of the relationships between indexes and lengths.
- CVE-2017-9766High
In Wireshark 2.2.7, PROFINET IO data with a high recursion depth allows remote attackers to cause a denial of service (stack exhaustion) in the dissect_IODWriteReq function.
- CVE-2017-9351High
In Wireshark versions 2.2.0 to 2.2.6 and 2.0.0 to 2.0.12, the DHCP dissector could read past the end of a buffer. This was addressed by extracting the Vendor Class Identifier more carefully.
- CVE-2017-9345High
In Wireshark versions 2.2.0 to 2.2.6 and 2.0.0 to 2.0.12, the DNS dissector could go into an infinite loop. This was addressed by trying to detect self-referencing pointers.
- CVE-2017-9343High
In Wireshark versions 2.2.0 to 2.2.6 and 2.0.0 to 2.0.12, the MSNIP dissector misuses a NULL pointer. This was addressed by validating an IPv4 address.
- CVE-2017-7748High
In Wireshark versions 2.2.0 to 2.2.5 and 2.0.0 to 2.0.11, the WSP dissector could enter an infinite loop, triggered by packet injection or a malformed capture file. This was addressed by adding a length check.
