Summary

Insight

Insight

Multiple flaws exist due to, - An improper validation of record sizes in 'wiretap/netscaler.c' script. - An improper incrementing of certain sequence value in 'epan/dissectors/packet-rtmpt.c' script. - An improper validation of the relationships between lengths and offsets in 'wiretap/k12.c' script. - An error related to constraining packet lateness in 'pan/dissectors/packet-iax2.c' script. - An improper validation of the capability length in 'epan/dissectors/packet-wsp.c' script. - In 'epan/dissectors/packet-ldss.c' memory was not allocated for a certain data structure. - If the packet size field in a packet header is null, the offset to read from will not advance, causing continuous attempts to read the same zero length packet.
