CVE-2026-55079 Coder's unbounded memory allocation in provisioner file upload allows authenticated denial of service

Coder allows organizations to provision remote development environments via Terraform. Starting in version 2.24.0 and prior to versions 2.29.7, 2.32.7, 2.33.8, and 2.34.2, NewDataBuilder in provisionersdk/proto/dataupload.go allocated a byte slice using the client-supplied FileSize from a...

CVE-2026-55079

Coder’s GO-based provisioner vulnerability arises from NewDataBuilder allocating a byte slice using client-supplied FileSize without an upper bound. The DRPC wire limit is 4 MiB, but FileSize could be much larger, causing memory exhaustion and potential denial of service when an authenticated use...

SUSE CVE-2026-55379

Pillow is a Python imaging library. Prior to 12.3.0, PIL/BdfFontFile.py bdfchar read the BBX width and height field from a BDF font file and passed attacker-controlled dimensions to Image.new without calling Image.decompressionbombcheck, bypassing Pillow's documented decompression bomb protection...

CVE-2026-54060

A flaw was found in Pillow, a Python imaging library. When processing a specially crafted font file, the library's font compilation function does not adequately check for excessive memory allocation. This oversight allows a remote attacker to trigger an unreasonable consumption of system memory,...

PYSEC-2026-899 protobuf-cpp and protobuf-python have potential Denial of Service issue

Summary A message parsing and memory management vulnerability in ProtocolBuffer’s C++ and Python implementations can trigger an out of memory OOM failure when processing a specially crafted message, which could lead to a denial of service DoS on services using the libraries. Reporter: ClusterFuzz...

CVE-2026-14684

A flaw was found in HdrHistogram. A local attacker can exploit a vulnerability in the decodeFromByteBuffer function by manipulating the numberOfSignificantValueDigits argument. This manipulation leads to uncontrolled memory allocation, which can result in a Denial of Service DoS condition, making...
