CVE-2017-6009 : Exploit Details and Defense Strategies
Learn about CVE-2017-6009, a buffer overflow vulnerability in icoutils 0.31.1 impacting the wrestool component. Find out how to mitigate and prevent this issue.
A vulnerability has been found in icoutils 0.31.1, specifically in the "restable.c" source file, where a buffer overflow is occurring. The lack of size checking for the "len" parameter in the "decode_ne_resource_id" function allows the parameter to become a negative integer, causing the memcpy operation to fail and impacting the wrestool component.
