CVE-ID: CVE-2019-5481
CWE-ID:
CWE-415 - Double Free
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform denial of service (DoS) attack.
The vulnerability exists due to a boundary error when processing very large blocks during Kerberos FTP data transfer. A remote attacker that controls malicious FTP server can send large blocks of data to the curl client, trigger a double-free error and crash the application.

2) Heap-based buffer overflow
EUVDB-ID: #VU21059
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-5482
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 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.
