JLSEC-2026-404

An allocation of resources without limits or throttling vulnerability exists in curl v7.88.0 based on the "chained" HTTP compression algorithms, meaning that a server response can be compressed multiple times and potentially with differentalgorithms. The number of acceptable "links" in this...

JLSEC-2026-393

curl 7.84.0 supports "chained" HTTP compression algorithms, meaning that a serverresponse can be compressed multiple times and potentially with different algorithms. The number of acceptable "links" in this "decompression chain" was unbounded, allowing a malicious server to insert a virtually...

When libcurl is asked to perform automatic gzip decompression of content-encoded HTTP responses with the CURLOPTACCEPTENCODING option, using zlib 1.2.0.3 or older, an attacker-controlled integer overflow would make libcurl perform a buffer overflow...

Security Bulletin: Denial of Service in urllib3 via Unbounded Decompression of Redirect Responses

Summary urllib3 is an HTTP client library for Python. urllib3's streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once. urllib3 can perform decoding or decompression based on t...

Security Bulletin:urllib3 Unbounded Decompression Chain Enables Denial of Service

Summary urllib3 is a user-friendly HTTP client library for Python. Starting in version 1.24 and prior to 2.6.0, the number of links in the decompression chain was unbounded allowing a malicious server to insert a virtually unlimited number of compression steps leading to high CPU usage and massiv...

CVE-2026-6535

A flaw was found in Wireshark's dissection engine. A remote attacker could exploit this vulnerability by sending a specially crafted packet. This could trigger a zlib decompression crash, leading to a denial of service and making the application unresponsive or causing it to terminate unexpectedl...
