description |
[Impact]
libmozjs24 does not support 48-bit virtual addresses on arm64. 48-bit virtual addresses are enabled in the Ubuntu 16.04 kernel (though not on the kernel used on the buildds). This causes applications to crash.
[Test Case]
apt source mozjs24
sudo apt build-dep -y mozjs24
sudo apt install -y fakeroot
cd mozjs24-24.2.0
fakeroot make -f debian/rules build
cd js/src
make
./jsapi-tests/jsapi-tests
Unpatched source crashes for me immediately on xenial:
dannf@mustang:~/mozjs24-24.2.0/js/src$ ./jsapi-tests/jsapi-tests
testXDR_sourceMap
Segmentation fault
All tests pass w/ patched source
[Regression Risk]
I'd suggest running through the jsapi-tests on each supported Ubuntu architecture. I've only ran it on arm64 so far. |
[Impact]
libmozjs24 does not support 48-bit virtual addresses on arm64. 48-bit virtual addresses are enabled in the Ubuntu 16.04 kernel (though not on the kernel used on the buildds). This causes applications to crash.
[Test Case]
= mozjs =
$ sudo apt install couchdb-bin
$ couchjs a.js
Segmentation fault
= mozjs24 =
$ cat a.js
print("hello")
$ js24 a.js
Segmentation fault
[Regression Risk]
The fix for mozjs24 is ifdef'd to only apply to arm64. Since arm64 is currently segfaulting with a very simple program, there's very little chance of making things worse. |
