1) Stack-based buffer overflow (CVE-ID: CVE-2013-2236)

CWE-ID: CWE-121 - Stack-based buffer overflow

CVSSv4: 6.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the new_msg_lsa_change_notify function in the OSPFD API (ospf_api.c) when processing a large LSA. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


2) Arbitrary code execution (CVE-ID: CVE-2016-2342)

CWE-ID: CWE-120 - Buffer overflow
