Description
This security bulletin contains information about 3 secuirty vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2023-42503)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources when parsing .tar archives. A remote attacker can pass a specially crafted archive to the application and consume excessive CPU usage.
2) Buffer overflow (CVE-ID: CVE-2022-3602)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing the email address field inside X.509 certificate. A remote attacker can supply a specially crafted certificate to the application, trigger a 4-byte 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 either a CA signs the malicious certificate or for the application to continue certificate verification despite failure to construct a path to a trusted issuer.
3) Heap-based buffer overflow (CVE-ID: CVE-2023-38545)
The 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).
