Security Issue Details
Rockwell Automation uses the latest version of the CVSS scoring system to assess security issues. The security of our products is important to us as your industrial automation supplier. This irregularity was found internally during routine testing and is being reported based on our commitment to customer transparency and to improving production environments.
CVE-2021-35940 IMPACT
An out of bounds array read security issue was fixed in the apr_time_exp*() function in the Apache Portable Runtime v1.6.3 (CVE-2017-12613). The fix for this issue was not carried forward to the APR 1.7.x branch causing version 1.7.0 to regress compared to 1.6.3. Therefore it is vulnerable to the same issue. If exploited, a threat actor could potentially read confidential data or cause the software to become unavailable.
