Adam Zabrocki has reported a vulnerability in Apache, which can be exploited by malicious people to potentially compromise a vulnerable system.
The vulnerability is caused due to an integer truncation error within the "ap_proxy_send_fb()" function in src/modules/proxy/proxy_util.c, which can be exploited to e.g. cause a heap-based buffer overflow.
Note: This only affects systems where the size of the "long" datatype is bigger than than the size of the "int" datatype (e.g. on 64-bit systems).
The vulnerability is reported in version 1.3.41. Other versions may also be affected.
