pip absolute path traversal during download from malicious package indexes

Allocation of Resources Without Limits or Throttling vulnerability in ninenines cowboy allows an unauthenticated remote attacker to exhaust connection process memory over HTTP/1.1.

The HTTP/1.1 handler in cowboyhttp enforces the maxheaders limit by counting the number of distinct header names in a map (maps:size(Headers)). When a request contains multiple header lines with the same name, the values are concatenated into a single ever-growing binary stored under that one map key (", " for regular headers, "; " for cookies), so the map size stays at one and the maxheaders cap (default 100) is never reached. Because no accumulator bounds the total number of header lines or the total byte size of the header block (only per-line maxheadernamelength and maxheadervaluelength apply), an unauthenticated client can send an arbitrary number of header lines with the same name and grow the connection process's binary memory to arbitrary size within the request window.

The impact per connection is bounded by requesttimeout (default 5 seconds, not reset by header data), and by maxheapsize when set (the offending connection process is killed once its heap grows past the limit). When maxheapsize is left at the default (unset), sustained abuse can drive the Erlang VM into out-of-memory conditions.

This issue affects cowboy from 2.0.0-pre.4 before 2.18.0.

A security vulnerability has been detected in libssh2 up to 1.11.1. The impacted element is the function userauthpassword of the file src/userauth.c. Such manipulation of the argument usernamelen/passwordlen leads to integer overflow. The attack may be launched remotely. The name of the patch is 256d04b60d80bf1190e96b0ad1e91b2174d744b1. A patch should be applied to remediate this issue.
