SB2026042522 - openEuler 24.03 LTS SP3 update for python-pillow

Description

This security bulletin contains information about 3 vulnerabilities.

1) Resource exhaustion (CVE-ID: CVE-2026-40192)

CWE-ID: CWE-400 - Resource exhaustion

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

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to uncontrolled resource consumption in the FITS image decoder when parsing a specially crafted GZIP-compressed FITS file. A remote attacker can supply a specially crafted FITS file to cause a denial of service.

The issue can result in unbounded memory consumption, leading to an out-of-memory crash or severe performance degradation.

2) 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.

3) 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.
