Description
Exim is prone to a remote overflow condition. The string_format function fails to properly sanitize user-supplied input resulting in a heap buffer overflow. With a specially crafted request, a local attacker can potentially cause arbitrary code execution.
Currently, there are no known workarounds or upgrades to correct this issue. However, Exim Development Team has released a patch to address this vulnerability.
