Issue Overview:
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. (CVE-2021-35940)
Integer Overflow or Wraparound vulnerability in apr_base64 functions of Apache Portable Runtime Utility (APR-util) allows an attacker to write beyond bounds of a buffer. This issue affects Apache Portable Runtime Utility (APR-util) 1.6.1 and prior versions. (CVE-2022-24963)
