[SECURITY] Fedora 43 Update: perl-Sereal-5.005-1.fc43

Sereal is an efficient, compact-output, binary and feature-rich serialization protocol. The Perl encoder is implemented as the Sereal::Encoder module, the Perl decoder correspondingly as Sereal::Decoder. This Sereal module is a very thin wrapper around both Sereal::Encoder and Sereal::Decoder. It...

DICOM, Pydicom, GDCM, and Orthanc: A technical tour of what really happens in the heap

Over the last decade, DICOM parsing has become an active research topic. The reason is simple: DICOM is both critical and complicated. Hospitals rely on DICOM-based PACS systems, and those systems often automatically ingest files received over the network. That means malformed data could directly...

CVE-2026-42328

go-ipld-prime is an implementation of the InterPlanetary Linked Data IPLD spec interfaces, a batteries-included codec implementations of IPLD for CBOR and JSON, and tooling for basic operations on IPLD objects. Prior to 0.23.0, the DAG-CBOR and DAG-JSON decoders recurse on each nested map or list...

freerdp: FreeRDP has a division-by-zero in ADPCM decoders when `nBlockAlign` is 0

A division by zero flaw has been discovered in FreeRDP. This division by zero exists in the MS-ADPCM and IMA-ADPCM decoders when nBlockAlign is 0, leading to a crash. In libfreerdp/codec/dsp.c, both ADPCM decoders use size % blocksize where blocksize = context-common.format.nBlockAlign. The...

freerdp: FreeRDP has an out-of-bounds read in ADPCM decoders due to missing predictor/step_index bounds checks

An out of bounds read flaw has been discovered in FreeRDP. This out-of-bounds read exists in the MS-ADPCM and IMA-ADPCM decoders due to unchecked predictor and stepindex values from input data. An attacker may be able to leverage this weakness to leak global data...

freerdp: FreeRDP: Denial of Service via crafted audio data in RDP

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol RDP. A remote attacker can exploit a sizet underflow vulnerability in the IMA-ADPCM and MS-ADPCM audio decoders by sending specially crafted audio data over the RDPSND audio channel. This underflow leads to a...

GHSA-W8J3-PQ8G-8M7W iskorotkov/avro: CPU Exhaustion in Decoder

CPU Exhaustion in Avro Decoder via Unbounded Block-Count Iteration Summary The Avro array and map decoders looped over an attacker-controlled block-count value without checking the underlying reader's error state inside the loop body. Reader.ReadBlockHeader returns the count as a Go int, which is...
