xz: XZ Utils: Denial of Service via buffer overflow in index decoding
A flaw was found in XZ Utils. When the lzmaindexdecoder function processes an empty index, and a subsequent lzmaindexappend operation is performed, insufficient memory is allocated. This can lead to a buffer overflow, potentially causing a denial of service DoS for affected systems...
