Denial Of Service (DoS)

httplib2 is vulnerable to Denial Of Service DoS. The vulnerability is due to unbounded decompression of HTTP response bodies encoded with gzip or deflate, which allows a malicious server to return a compression bomb that exhausts client memory and causes a crash or out-of-memory condition...

Ubuntu 16.04 LTS : Ruby vulnerabilities (USN-8556-1)

The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8556-1 advisory. It was discovered that the Net::IMAP client in Ruby did not properly sanitize Symbol arguments passed to IMAP commands. A remote attacker controlling a...

CVE-2026-44981

CrowdSec offers crowdsourced protection against malicious IPs. From 1.7.0 until 1.7.8, the LAPI router used gin-contrib/gzip with DefaultDecompressHandle globally in pkg/apiserver/controllers/controller.go, causing /v1/watchers and /v1/watchers/login to decompress unauthenticated gzip-compressed...

CVE-2026-44981 CrowdSec LAPI: Denial of Service via Unbounded Gzip Decompression

CrowdSec offers crowdsourced protection against malicious IPs. From 1.7.0 until 1.7.8, the LAPI router used gin-contrib/gzip with DefaultDecompressHandle globally in pkg/apiserver/controllers/controller.go, causing /v1/watchers and /v1/watchers/login to decompress unauthenticated gzip-compressed...

CVE-2026-44981

CrowdSec LAPI is affected. The LAPI router uses gin-contrib/gzip with DefaultDecompressHandle globally in pkg/apiserver/controllers/controller.go, causing unauthenticated gzip payloads to be decompressed on /v1/watchers and /v1/watchers/login without a maximum decompressed size, which can trigger...

USN-8556-1: Ruby vulnerabilities

It was discovered that the Net::IMAP client in Ruby did not properly sanitize Symbol arguments passed to IMAP commands. A remote attacker controlling a malicious IMAP server, or able to influence command arguments, could use this to inject arbitrary IMAP commands via CRLF sequences. CVE-2026-4225...
