Insight

Insight

Multiple flaws exist due to, - The 'dissect_nhdr_extopt' function in 'epan/dissectors/packet-lbmc.c' script in the LBMC dissector does not validate length values. - The 'wiretap/nettrace_3gpp_32_423.c' script in the 3GPP TS 32.423 Trace file parser does not ensure that a '\0' character is present at the end of certain strings. - The 'epan/dissectors/packet-hiqnet.c' script in the HiQnet dissector does not validate the data type. - The 'epan/dissectors/packet-x509af.c' script in the X.509AF dissector mishandles the algorithm ID. - The 'epan/dissectors/packet-http2.c' script in the HTTP/2 dissector does not limit the amount of header data. - The 'dissect_ber_constrained_bitstring' function in 'epan/dissectors/packet-ber.c' script in the ASN.1 BER dissector does not verify that a certain length is nonzero. - A heap-based buffer overflow error in 'wiretap/vwr.c' script in the Ixia IxVeriWave file parser. - An error in NFS dissector. - 'epan/dissectors/packet-spice.c' script in the SPICE dissector in mishandles capability data. - 'epan/dissectors/packet-ieee80211.c' script in the IEEE 802.11 dissector mishandles the Grouping subfield.
