Comment 7 Tomas Hoger 2021-08-27 08:14:04 UTC

The fix for the apr issue CVE-2017-12613 (see bug 1506523 for more details) that was applied upstream in version 1.6.3 was not applied to 1.7 branch and hence it was regressed in upstream version 1.7.0.  A new CVE-2021-35940 was assigned for the regression.

Upstream announcement:

Upstream commit:

http://svn.apache.org/viewvc?view=revision&revision=1891198

Upstream patch for 1.7 - it's a subset of the changes in the above commit, removing changes related to other fix included in the commit:

https://dist.apache.org/repos/dist/release/apr/patches/apr-1.7.0-CVE-2021-35940.patch

The fix should be included in upstream version 1.7.1, which has not been released yet.
