CVE-2026-19027 HDF5 out-of-bounds heap read in N-Bit filter decompression

The H5Znbitdecompressonebyte, H5Znbitdecompressonenooptype, and H5Znbitdecompressoneatomic functions in H5Znbit.c in HDF5 prior to 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...

CVE-2026-19027

The H5Znbitdecompressonebyte, H5Znbitdecompressonenooptype, and H5Znbitdecompressoneatomic 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...

CVE-2026-19027

The CVE-2026-19027 entry describes an out-of-bounds heap read in HDF5 before 2.3.0 due to the N-Bit filter decompression routines. Specifically, H5Z__nbit_decompress_one_byte, H5Z__nbit_decompress_one_nooptype, and H5Z__nbit_decompress_one_atomic in H5Znbit.c advance a read index into the compres...

httplib2: httplib2: Denial of Service via unbounded decompression of HTTP response bodies

A flaw was found in httplib2, a Python HTTP client library. This vulnerability allows a malicious or compromised HTTP server to send a small compressed data payload that, when decompressed by httplib2, expands to an extremely large size in memory. This unbounded decompression can lead to a Denial...
