Description

This security bulletin contains information about 6 vulnerabilities.


1) Infinite loop (CVE-ID: CVE-2024-55565)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote user to perform a denial of service (DoS) attack.

The vulnerability exists due to infinite loop. A remote user can consume all available system resources and cause denial of service conditions.


2) Improper authorization (CVE-ID: CVE-2024-45337)

CWE-ID: CWE-285 - Improper Authorization

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:P/U:Green


The vulnerability allows a remote attacker to gain unauthorized access to the application.

The vulnerability exists due to improper authorization caused by improper usage of the ServerConfig.PublicKeyCallback callback. A remote attacker can bypass authorization in certain cases and gain access to the application.


3) Out-of-bounds write (CVE-ID: CVE-2019-12900)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the BZ2_decompress() function in decompress.c. A remote attacker can create a specially crafted archive, trick the victim into opening it using the affected library, trigger out-of-bounds write and execute arbitrary code on the target system.

4) OS Command Injection (CVE-ID: CVE-2024-9287)

CWE-ID: CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to improper input validation in the venv module when creating a virtual environment. A local user can pass specially crafted strings to the application and execute arbitrary OS commands on the target system.


5) Input validation error (CVE-ID: CVE-2024-11168)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to bypass security restrictions.

The vulnerability exists due to insufficient validation of bracketed hosts (e.g. []) within the urllib.parse.urlsplit() and urlparse() functions allowing hosts that weren't IPv6 or IPvFuture. A remote attacker can pass specially crafted IP address to the application to bypass implemented IP-based security checks or perform SSRF attacks.


6) Resource exhaustion (CVE-ID: CVE-2024-34156)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to encoding/gob does not properly control consumption of internal resources when calling Decoder.Decode. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.

Note, this vulnerability is related to #VU66068 (CVE-2024-34156).
