Name of the Vulnerable Software and Affected Versions Connman versions 1.40 and earlier

Description An issue was discovered in the DNS proxy in Connman, where the forward dns reply function mishandles a strnlen call, leading to an out-of-bounds read. This could allow a remote attacker to access confidential information or cause a denial of service.

Recommendations For Connman versions 1.40 and earlier, as a temporary workaround, consider disabling the forward dns reply function until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
