postfix: buffer over-read via malformed enhanced status code

A flaw was found in Postfix. This issue occurs when processing enhanced status codes, specifically an enhanced status code that lacks text following the third number. Depending on the configuration of the server, this allows a remote attacker to cause a buffer over-read of only 1 byte, leading to...

EUVD-2026-53676

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-2026-67873

A heap-based buffer overflow exists in lib60870-C 2.4.0 in the server-side FileSegment ASDU encoding path. The issue occurs because FileSegmentencode validates only the standalone segment length via FileSegmentGetMaxDataSize and does not verify the residual capacity of the current ASDU frame befo...
