The libproxy packages provide a library that handles all the details of proxy configuration. The libproxy library provides a stable external API, dynamic adjustment to changing network topology, and small core footprint. It does not use external dependencies within the libproxy core, however libproxy plug-ins may have dependencies.

Security Fix(es):

  • libproxy: sending more than 102400 bytes in PAC without a Content-Length present could result in buffer overflow (CVE-2020-26154)

  • libproxy: uncontrolled recursion via an infinite stream response leading to stack exhaustion (CVE-2020-25219)
