CVE-2026-19027

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...

netty: io.netty/netty-codec-http: Netty: Denial of Service via SPDY header decompression amplification

A flaw was found in Netty, a network application framework. A remote attacker could exploit a vulnerability in the SPDY header decoding process. By sending a specially crafted, small compressed header block, the attacker can cause it to expand significantly during decompression, leading to...

io.netty/netty-codec-http: Netty: Memory exhaustion in netty-codec-http (decompression bomb)

A flaw was found in the Netty netty-codec-http component. A remote attacker can send HTTP requests containing highly compressed data. The HTTP decoder in netty-codec-http fails to properly limit the decompression of this content, causing the system to consume excessive memory. This can lead to...

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...
