SUSE CVE-2026-45352

cpp-httplib is a C++11 single-file header-only cross platform HTTP/HTTPS library. Prior to 0.43.4, negative chunk-size in chunked Transfer-Encoding causes unbounded memory allocation and process crash. The ChunkedDecoder::readpayload function in cpp-httplib httplib.h parses the chunk-size field o...

CVE-2026-45352

A flaw was found in cpp-httplib, a C++ HTTP/HTTPS library. A remote attacker could exploit this vulnerability by sending a specially crafted HTTP request that includes a negative chunk-size in the chunked Transfer-Encoding. This incorrect parsing leads to unbounded memory allocation, causing the...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to improper validation of the chunk-size field in chunked Transfer-Encoding within the ChunkedDecoder::readpayload function. An attacker can cause unbounded memory allocation and...

CVE-2026-45352

The CVE-2026-45352 issue affects cpp-httplib (header-only HTTP/HTTPS library). Before version 0.43.4, the ChunkedDecoder::read_payload routine parses the chunk-size in chunked Transfer-Encoding with std::strtoul(), which can silently accept a minus sign. This allows negative chunk sizes (e.g., "-...

UBUNTU-CVE-2017-13090

The retr.c:fdreadbody function is called when processing OK responses. When the response is sent chunked in wget before 1.19.2, the chunk parser uses strtol to read each chunk's length, but doesn't check that the chunk length is a non-negative number. The code then tries to read the chunk in piec...
