CVE-2014-7913 (GCVE-0-2014-7913)

Vulnerability from cvelistv5 – Published: 2015-07-30 00:00 – Updated: 2024-08-06 13:03

Summary

The print_option function in dhcp-common.c in dhcpcd through 6.9.1, as used in dhcp.c in dhcpcd 5.x in Android before 5.1 and other products, misinterprets the return value of the snprintf function, which allows remote DHCP servers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted message.

Severity

No CVSS data available.
