Summary

Moderate: gvisor-tap-vsock security and bug fix update

Details

A replacement for libslirp and VPNKit, written in pure Go. It is based on the network stack of gVisor and is used to provide networking for podman-machine virtual machines. Compared to libslirp, gvisor-tap-vsock brings a configurable DNS server and dynamic port forwarding.

Security Fix(es):

golang: net/http: memory exhaustion in Request.ParseMultipartForm (CVE-2023-45290)

CVE-2023-45290 (GCVE-0-2023-45290)

Vulnerability from cvelistv5 – Published: 2024-03-05 22:22 – Updated: 2025-02-13 17:14

Title

Memory exhaustion in multipart form parsing in net/textproto and net/http

Summary

When parsing a multipart form (either explicitly with Request.ParseMultipartForm or implicitly with Request.FormValue, Request.PostFormValue, or Request.FormFile), limits on the total size of the parsed form were not applied to the memory consumed while reading a single form line. This permits a maliciously crafted input containing very long lines to cause allocation of arbitrarily large amounts of memory, potentially leading to memory exhaustion. With fix, the ParseMultipartForm function now correctly limits the maximum size of form lines.

Severity ?

6.5 (Medium)
