CVE-2026-19028

H5Zfilterfletcher32 in H5Zfletcher32.c in HDF5 through 2.3.0 computes the data length to checksum by subtracting the 4-byte trailing checksum size from the input buffer size without checking that the buffer is at least 4 bytes, allowing a sizet underflow. This allows attackers to cause a denial o...

CVE-2026-64834

A flaw was found in FFmpeg. A remote attacker can exploit an infinite loop vulnerability in the RTP/ASF demuxer by sending a specially crafted stream.

Exim 4 before 4.94.2 has Improper Initialization that can lead to recursion-based stack consumption or other consequences. This occurs because use of certain getc functions is mishandled when a client uses BDAT instead of DATA...

HTTP/2: large amount of data requests leads to denial of service

A flaw was found in HTTP/2. An attacker can request a large amount of data by manipulating window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this queue can consume excess CPU, memory, or both, leading to a...
