USN-8115-1: pyOpenSSL vulnerabilities

Ubuntu Security Advisories
5 days 10 hours ago
It was discovered that pyOpenSSL incorrectly handled exceptions in the tlsext_servername callback. This could result in connections being accepted after an exception, contrary to expectations. (CVE-2026-27448) It was discovered that pyOpenSSL incorrectly handled the DTLS cookie generation callback. If a callback provided cookie values greater than 256 bytes, an attacker could use this issue to cause pyOpenSSL to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 24.04 LTS and Ubuntu 25.10. (CVE-2026-27459)

USN-8114-1: GVfs vulnerabilities

Ubuntu Security Advisories
5 days 10 hours ago
It was discovered that the GVfs FTP backend incorrectly handled IP addresses and ports returned by passive mode responses. A malicious remote server could possibly use this issue to help scan for open ports. (CVE-2026-28295) It was discovered that the GVfs FTP backend incorrectly handled crafted file paths. A remote attacker could use this issue to terminate or inject arbitrary FTP commands, or possibly execute arbitrary code. (CVE-2026-28296)

FEDORA-2026-e76feaf213 Packages in this update:
  • cpp-httplib-0.38.0-1.fc43
Update description: Update to 0.38.0 (rhbz#2447261)
  • Filename sanitization for path traversal prevention — Added sanitize_filename() to prevent path traversal attacks via malicious filenames in multipart uploads (83e98a2)

  • Symlink protection in static file server — Static file serving now detects and rejects symlinks that point outside the mount directory, preventing symlink-based directory traversal (f787f31)

  • Brotli compression support — Added Brotli (br) as a supported content encoding alongside gzip and deflate (ec1ffbc)

  • Accept-Encoding quality parameter parsing — The server now parses q= quality values in the Accept-Encoding header and selects the best encoding accordingly (bb7c7ab)
  • SSL proxy connection support — SSLClient can now establish connections through HTTPS proxies, with a new setup_proxy_connection method for cleaner proxy handling (f6ed5fc, b1bb2b7)

  • WebSocket ping interval runtime configuration — WebSocket ping interval can now be configured at runtime instead of only at compile time (257b266)

  • Benchmark test suite — Added benchmark tests and configurations for performance evaluation (ba0d0b8)

  • Unicode path component decoding tests — Added test coverage for Unicode characters in decode_path_component (43a54a3)

  • Documentation updates — Enhanced TLS backend documentation with platform-specific certificate handling details; clarified progress callback usage and user data handling in examples (511e3ef, 2e61fd3)

  • Fix port conflict in test — Fixed port number in OpenStreamMalformedContentLength test to avoid conflicts (4978f26)

  • Removed large data tests for GzipDecompressor and SSLClientServerTest that caused memory issues (5ecba74, 69d468f)

  • Enabled BindDualStack test (69d468f)

It was discovered that LibTIFF did not properly handle memory when processing certain images. An attacker could possibly use this issue to cause LibTIFF to crash, resulting in a denial of service. (CVE-2025-61143) It was discovered that LibTIFF did not properly handle memory when processing malformed TIFF directories. An attacker could possibly use this issue to cause LibTIFF to crash, resulting in a denial of service. (CVE-2025-61144)
