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...

TencentOS Server 4: rsync (TSSA-2025:0040)

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2025:0040 advisory. Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:...

CVE-2025-40129

In the Linux kernel, the following vulnerability has been resolved: sunrpc: fix null pointer dereference on zero-length checksum In xdrstreamdecodeopaqueauth, zero-length checksum.len causes checksum.data to be set to NULL. This triggers a NPD when accessing checksum.data in gsskrb5verifymicv2...

CVE-2025-40129

CVE-2025-40129 is a Linux kernel vulnerability addressed in Unity Linux/UTSA-2026-013110: sunrpc may dereference checksum.data due to a zero-length checksum in xdr_stream_decode_opaque_auth(), causing a null pointer dereference when gss_krb5_verify_mic_v2() accesses checksum.data. The patch ensur...

rsync: Heap Buffer Overflow in Rsync due to Improper Checksum Length Handling

A heap-based buffer overflow flaw was found in the rsync daemon. This issue is due to improper handling of attacker-controlled checksum lengths s2length in the code. When MAXDIGESTLEN exceeds the fixed SUMLENGTH 16 bytes, an attacker can write out of bounds in the sum2 buffer...

Astra Linux – Vulnerability in rsync
