MetricsAV:N/AC:L/Au:N/C:N/I:N/A:C
Name of the Vulnerable Software and Affected Versions libevent versions prior to 2.1.6-beta
Description The issue is related to a stack-based buffer overflow in the evutil parse sockaddr port function, which can be exploited by attackers to cause a denial of service, resulting in a segmentation fault. This can be achieved by providing a long string in brackets in the ip as string argument. The vulnerability allows remote attackers to disrupt service.
Recommendations For versions prior to 2.1.6-beta, update to version 2.1.6-beta or later to resolve the issue. As a temporary workaround, consider restricting input to the evutil parse sockaddr port function to prevent long strings in brackets from being processed.
