Description
This security bulletin contains information about 3 vulnerabilities.
1) Path traversal (CVE-ID: CVE-2022-22815)
CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences in path_getbbox() function in path.c. A remote attacker can send a specially crafted HTTP request and read arbitrary files on the system.
2) Out-of-bounds read (CVE-ID: CVE-2022-22816)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to buffer over-read during initialization of ImagePath.Path in path_getbbox() function in path.c. A remote attacker can pass a specially crafted file to the affected library and read contents of memory on the system.
3) Exposed dangerous method or function (CVE-ID: CVE-2022-22817)
CWE-ID: CWE-749 - Exposed Dangerous Method or Function
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 compromise the affected system.
The vulnerability exists due to usage of PIL.ImageMath.eval() function on arbitrary expressions. A remote attacker can pass specially crafted file to the library and execute arbitrary code on the system.
