CVE-2026-32641 Parseable: Unauthenticated Denial of Service via panic in Kinesis header parsing middleware

Parseable is a log analytics platform built for high-volume data ingestion and analysis. Prior to 3.0.0, src/handlers/http/middleware.rs uses unwrap while parsing the x-amz-firehose-common-attributes header before authentication. A remote unauthenticated attacker can supply non-UTF-8 header data,...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: usb: gadget: feem: Fixed a memory leak in eemunwrap. The existing code did not handle the failure case of usbepqueue in the command path, potentially leading to memory leaks. Improved error handling to free all allocated...

Astra Linux – Vulnerability in Heimdal, Samba

A heap-based buffer overflow vulnerability was discovered in Samba, specifically within the GSSAPI unwrapdes and unwrapdes3 routines of Heimdal. The DES and Triple-DES decryption routines in the Heimdal GSSAPI library allow for a length-limited write buffer overflow on memory allocated by malloc,...
