What is CVE-2020-13995?
CVE-2020-13995 is a critical memory corruption vulnerability in n/a, published on 25 Sep 2020. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
U.S. Air Force Sensor Data Management System extract75 has a buffer overflow that leads to code execution. An overflow in a global variable (sBuffer) leads to a Write-What-Where outcome. Writing beyond sBuffer will clobber most global variables until reaching a pointer such as DES_info or image_info. By controlling that pointer, one achieves an arbitrary write when its fields are assigned. The data written is from a potentially untrusted NITF file in the form of an integer. The attacker can gain control of the instruction pointer.
Weakness: CWE-787
