openssl: fix CVE-2023-464 and CVE-2023-465 
Apply two patches fixing low-severity vulnerabilities related to
certificate policies validation:

- Excessive Resource Usage Verifying X.509 Policy Constraints
  (CVE-2023-0464)
  Severity: Low
  A security vulnerability has been identified in all supported versions
  of OpenSSL related to the verification of X.509 certificate chains
  that include policy constraints.  Attackers may be able to exploit
  this vulnerability by creating a malicious certificate chain that
  triggers exponential use of computational resources, leading to a
  denial-of-service (DoS) attack on affected systems.
  Policy processing is disabled by default but can be enabled by passing
  the `-policy' argument to the command line utilities or by calling the
  `X509_VERIFY_PARAM_set1_policies()' function.

- Invalid certificate policies in leaf certificates are silently ignored
  (CVE-2023-0465)
  Severity: Low
  Applications that use a non-default option when verifying certificates
  may be vulnerable to an attack from a malicious CA to circumvent
  certain checks.
  Invalid certificate policies in leaf certificates are silently ignored
  by OpenSSL and other certificate policy checks are skipped for that
  certificate.  A malicious CA could use this to deliberately assert
  invalid certificate policies in order to circumvent policy checking on
  the certificate altogether.
  Policy processing is disabled by default but can be enabled by passing
  the `-policy' argument to the command line utilities or by calling the
  `X509_VERIFY_PARAM_set1_policies()' function.

Note: OpenSSL also released a fix for low-severity security advisory
CVE-2023-466.  It is not included here because the fix only changes the
documentation, which is not built nor included in any OpenWrt package.

Due to the low-severity of these issues, there will be not be an
immediate new release of OpenSSL.

README.md

OpenWrt logo

OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.

Sunshine!

Development

To build your own firmware you need a GNU/Linux, BSD or MacOSX system (case sensitive filesystem required). Cygwin is unsupported because of the lack of a case sensitive file system.

Requirements

You need the following tools to compile OpenWrt, the package names vary between distributions. A complete list with distribution specific packages is found in the Build System Setup documentation.

gcc binutils bzip2 flex python3 perl make find grep diff unzip gawk getopt
subversion libz-dev libc-dev rsync which

Quickstart

  1. Run ./scripts/feeds update -a to obtain all the latest package definitions defined in feeds.conf / feeds.conf.default

  2. Run ./scripts/feeds install -a to install symlinks for all obtained packages into package/feeds/

  3. Run make menuconfig to select your preferred configuration for the toolchain, target system & firmware packages.

  4. Run make to build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.

Related Repositories

The main repository uses multiple sub-repositories to manage packages of different categories. All packages are installed via the OpenWrt package manager called opkg. If you're looking to develop the web interface or port packages to OpenWrt, please find the fitting repository below.
