Detailsinfo

A vulnerability, which was classified as critical, was found in Apache Portable Runtime APR up to 1.6.2. This affects the function apr_exp_time*/apr_os_exp_time*. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

When apr_exp_time*() 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.

The bug was discovered 10/24/2017. The weakness was released 10/24/2017 (Website). The advisory is shared at lists.apache.org.
