CyberRota Analysis
AI-GeneratedLibevent versions prior to 2.1.13 and 2.2.2-alpha are vulnerable to an integer conversion flaw that allows an attacker to manipulate payload lengths, potentially leading to a denial of service through large allocation requests. This vulnerability poses a high risk, particularly for applications relying on Libevent for event notification, as it can disrupt service availability. Organizations using affected versions should prioritize upgrading to the patched releases to mitigate this risk.

Original NVD Description
Libevent is an event notification library. Prior to 2.1.13 and 2.2.2-alpha, libevent has an incorrect integer conversion in event_tagging.c when evtag_unmarshal_header uses evtag_decode_int to decode an attacker-controlled uint32 payload length and returns it as a signed int. Values above INT_MAX become negative or truncated, and evtag_unmarshal_string can use the converted value in allocation sizing, producing a wrapped large allocation request and denial of service. This issue is fixed in versions 2.1.13 and 2.2.2-alpha.
