Integer Overflow Vulnerabilities in Apache Portable Runtime Library

CVE-2009-2412

Summary

The Apache Portable Runtime (APR) library contains multiple integer overflow vulnerabilities that can be exploited by remote attackers. Attackers may cause a denial of service by triggering application crashes or, in some cases, execute arbitrary code. This is achieved by crafting specific calls to functions such as allocator_alloc or apr_palloc in APR, or implementing designed calls to apr_rmm_malloc, apr_rmm_calloc, or apr_rmm_realloc in APR-util. An analysis of the memory management functions reveals risks where buffer overflows can emerge, leading to potentially severe consequences for affected applications.
