Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Heap-based buffer overflow
EUVDB-ID: #VU81865
Risk: High
CVSSv4.0: 7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber]
CVE-ID: CVE-2023-38545
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the SOCKS5 proxy handshake. A remote attacker can trick the victim to visit a malicious website, 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 but requires that SOCKS5 proxy is used and that SOCKS5 handshake is slow (e.g. under heavy load or DoS attack).
Update the affected package curl to the latest version.

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.
2) External control of file name or path
EUVDB-ID: #VU81863
Risk: Low
CVSSv4.0: 0.1 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2023-38546
CWE-ID:
CWE-73 - External Control of File Name or Path
Exploit availability: No
DescriptionThe vulnerability allows an attacker to inject arbitrary cookies into request.
The vulnerability exists due to the way cookies are handled by libcurl. If a transfer has cookies enabled when the handle is duplicated, the
cookie-enable state is also cloned - but without cloning the actual
cookies. If the source handle did not read any cookies from a specific
file on disk, the cloned version of the handle would instead store the
file name as none (using the four ASCII letters, no quotes).
none - if such a file exists and is readable in the current directory of the program using libcurl.
Mitigation
Update the affected package curl to the latest version.
