Description SMASH SMASH 2024-02-05 10:06:44 UTC

libexpat through 2.5.0 allows a denial of service (resource consumption) because many full reparsings are required in the case of a large token for which multiple buffer fills are needed.

Tracking as affected:
- SUSE:ALP:Source:Standard:1.0
- SUSE:Carwos:1/expat
- SUSE:SLE-11:Update/expat (in reactive support)
- SUSE:SLE-12:Update/expat

Comment 4 David Anes 2024-02-12 14:47:09 UTC

From 2.6.0 release notes:

> Backporters should be careful to no omit parts of
> pull request #789 and to include earlier pull request #771,
> in order to not break the fix.

Therefore, patches are in:
- https://github.com/libexpat/libexpat/pull/789
- https://github.com/libexpat/libexpat/pull/771

Comment 5 David Anes 2024-02-14 09:52:32 UTC

Factory request is on-going, as the update to 2.6.0 breaks other packages (I already notified their maintainers):
* https://build.opensuse.org/request/show/1146280

Comment 12 David Anes 2024-02-21 08:17:33 UTC

There is a discussion in https://github.com/libexpat/libexpat/pull/789 regarding backporting.

It seems, not only this has to be backported:
- https://github.com/libexpat/libexpat/pull/789
- https://github.com/libexpat/libexpat/pull/771

But also:
- https://github.com/libexpat/libexpat/pull/817 (this one is newer than 2.6.0, but fixes some flaky tests).
- https://github.com/libexpat/libexpat/pull/788
- https://github.com/libexpat/libexpat/pull/783
- https://github.com/libexpat/libexpat/pull/758
- https://github.com/libexpat/libexpat/pull/757
- https://github.com/libexpat/libexpat/pull/755
- https://github.com/libexpat/libexpat/pull/753
- https://github.com/libexpat/libexpat/pull/745

Comment 13 Andreas Taschner 2024-02-23 13:15:03 UTC
