Description

This security bulletin contains information about 1 security vulnerability.


1) Integer overflow (CVE-ID: CVE-2018-14938)

The vulnerability allows a remote attacker to obtain potentially sensitive information or cause DoS condition.

The vulnerability exists in the handle_80211 and handle_prism functions, as defined in the wifipcap/wifipcap.cpp source code file due to an integer overflow condition that could occur during caplen processing. A remote attacker can trigger memory corruption, and if the caplen is less than 144, trigger an out-of-bounds read in the handle_80211 function, which could allow access to sensitive information or cause a denial of service (DoS) condition on the targeted system.
