Heap-based buffer overflow in cURL - CVE-2019-5482

Vulnerability identifier: #VU21059

CSH Severity: Medium

CVSS v4: 7.1 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2019-5482

CWE-ID: CWE-122

Exploitation vector: Remote access

Exploit availability: No public exploit available

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

The vulnerability exists due to a boundary error within the tftp_receive_packet() function when processing TFTP data. A remote attacker can send specially crafted TFTP response to the vulnerable curl client, trigger 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.
