apr: Security fix for CVE-2021-35940
Source: https://dist.apache.org
MR: 112793
Type: Security Fix
Disposition: Backport from https://dist.apache.org/repos/dist/release/apr/patches/apr-1.7.0-CVE-2021-35940.patch
ChangeID: c8247210204ffcc7d1425e3d60f077ad3dd54ebc
Description:
An out-of-bounds array read in the apr_time_exp*() functions was fixed in the
Apache Portable Runtime 1.6.3 release (CVE-2017-12613). The fix for this issue
was not carried forward to the APR 1.7.x branch, and hence version 1.7.0 regressed
compared to 1.6.3 and is vulnerable to the same issue.
