BIT-LIBPYTHON-2025-13836 Excessive read buffering DoS in http.client

When reading an HTTP response from a server, if no read amount is specified, the default behavior will be to use Content-Length. This allows a malicious server to cause the client to read large amounts of data into memory, potentially causing OOM or other DoS...

GHSA-MF9V-MFXR-J63J urllib3: Decompression-bomb safeguards bypassed in parts of the streaming API

Impact 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 decompression based on the HTTP Content-Encoding header e.g., gzip, deflate, br, or...

CoreDNS 安全漏洞

CoreDNS is a DNS server within the CoreDNS community. Versions of CoreDNS prior to 1.14.3 contained a security vulnerability. This vulnerability stemmed from the DNS-over-QUIC server, where remote clients opened numerous QUIC streams and sent only 1 byte of data. This could lead to unlimited...

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...

Astra Linux – Vulnerability in Netty

The Snappy frame decoder function does not limit the chunk length, which can lead to excessive memory usage. In addition, it may also buffer reserved skipable chunks until the entire chunk is received, which can also result in excessive memory usage. This vulnerability can be exploited by providi...

Astra Linux – Vulnerability in pillow

In Pillow before 8.1.2, attackers can cause a denial of service due to excessive memory consumption. This occurs because the reported size of the contained image is not properly checked for an ICNS container. As a result, a memory allocation attempt can be quite large...
