Build Asterisk 20.5 LTS with pjproject 2.14 due to CVE-2023-38703

Hey!

I’m trying to build and install Asterisk 20.5 LTS.

There is a security vulnerability in pjproject that was fixed in version 2.14:
CVE-2023-38703, which seems to be somewhat critical:

This vulnerability’s impact may range from unexpected application termination to control flow hijack/memory corruption.
→ I’d love to include a link to the Github Security Advisory but the forum software says new users aren’t allowed to use 2 links…

However, if I run ./configure --with-pjproject-bundled, the Asterisk build process downloads 2.13.1:

checking for embedded pjproject (may have to download)… configuring
[pjproject] Downloading https://raw.githubusercontent.com/asterisk/third-party/master/pjproject/2.13.1/pjproject-2.13.1.tar.bz2 to /tmp/pjproject-2.13.1.tar.bz2

What should I do? Will there be a fixed release in near time?

I tried to download pjproject from pjsip.org and build it on my own. That worked so far.

But when I try to make Asterisk after ./configure --without-pjproject-bundled, it finally terminates with an error:

[LD] chan_pjsip.o pjsip/cli_commands.o pjsip/dialplan_functions.o → chan_pjsip.so

Thank you for any advice!

See See Use-after-free in SRTP media transport · Advisory · pjsip/pjproject · GitHub for the Security Advisory.

Asterisk doesn’t use that functionality. We also pull in any applicable security fixes when they occur and do our own release.
