| Vetor | AV:N/AC:L/Au:N/C:P/I:P/A:P |
Name of the Vulnerable Software and Affected Versions
Exim versions prior to 4.76
Description
The issue is related to a format string vulnerability in the
dkim exim verify finish function. This vulnerability might allow remote attackers to execute arbitrary code or cause a denial of service, such as a daemon crash, via format string specifiers in data used in DKIM logging. For example, an identity field containing a % (percent) character could trigger this issue.Recommendations
For versions prior to 4.76, update to version 4.76 or later to resolve the issue. As a temporary workaround, consider restricting the use of format string specifiers in DKIM logging data to minimize the risk of exploitation.
