CVE-ID: CVE-2023-0288
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the ml_append_int() function in memline.c. A remote attacker can trick the victim to open a specially crafted file, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
