A null pointer dereference bug affects the 16.02 and many old versions of p7zip. A lack of null pointer check for the variable folders.PackPositions in function CInArchive::ReadAndDecodePackedStreams in CPP/7zip/Archive/7z/7zIn.cpp, as used in the 7z.so library and in 7z applications, will cause a crash and a denial of service when decoding malformed 7z files.

p7zip 16.02 was discovered to contain a heap-buffer-overflow vulnerability via the function NArchive::NZip::CInArchive::FindCd(bool) at CPP/7zip/Archive/Zip/ZipIn.cpp. NOTE: the Supplier has found that this is not a buffer overflow; at most an out-of-bounds read can occur.
