Vulnerability Title
HDF5 out-of-bounds heap read in N-Bit filter decompression
Vulnerability Description
The H5Z__nbit_decompress_one_byte, H5Z__nbit_decompress_one_nooptype, and H5Z__nbit_decompress_one_atomic functions in H5Znbit.c in HDF5 through 2.3.0 advance a read index into the compressed chunk buffer without bounding it against the buffer's actual size. This allows attackers to cause an out-of-bounds heap read, and in constrained cases disclosure of adjacent heap memory into decompressed dataset values, via a crafted HDF5 file whose N-Bit filter parameters describe more decompressed data than the stored compressed chunk actually contains, triggered via H5Dread, e.g. by the h5ls or h5repack tools.

Vulnerability Title
HDF Group hdf5 缓冲区错误漏洞
Vulnerability Description
HDF Group hdf5是HDF Group组织的一个支持海量数据存储与管理的文件格式库。 HDF Group hdf5 2.3.0及之前版本存在缓冲区错误漏洞,该漏洞源于H5Znbit.c中函数对压缩块缓冲区读取索引未进行边界限制,攻击者通过特制HDF5文件触发,可能导致越界堆读取和相邻堆内存泄露。
