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.

An update of the apr package has been released.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-016 advisory.

  - 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_encode functions of Apache Portable Runtime (APR)     allows an attacker to write beyond bounds of a buffer. This issue affects Apache Portable Runtime (APR)     version 1.7.0. (CVE-2022-24963)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-1936 advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of apr installed on the remote host is prior to 1.7.2. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2023-032-01 advisory.

  - When apr_time_exp*() or apr_os_exp_time*() functions are invoked with an invalid month field value in     Apache Portable Runtime APR 1.6.2 and prior, out of bounds memory may be accessed in converting this value     to an apr_time_exp_t value, potentially revealing the contents of a different static heap value or     resulting in program termination, and may represent an information disclosure or denial of service     vulnerability to applications which call these APR functions with unvalidated external input.

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Ubuntu 16.04 ESM host has packages installed that are affected by a vulnerability as referenced in the USN-5056-1 advisory.

    It was discovered that APR incorrectly handled certain inputs. An attacker could possibly use this issue     to expose sensitive information.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
