Description

This security bulletin contains information about 7 vulnerabilities.


1) Out-of-bounds read (CVE-ID: CVE-2026-54058)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to disclose sensitive information or cause a denial of service.

The vulnerability exists due to an out-of-bounds read in the PyImaging_MapBuffer mmap path used with the McIdas AREA plugin when processing a crafted image file opened from a filename. A remote attacker can supply a specially crafted McIdas AREA image with an undersized row stride to disclose sensitive information or cause a denial of service.

The issue is reachable when Pillow memory-maps an uncompressed raw tile in a mode listed in Image._MAPMODES, and pixel access operations such as Image.tobytes(), getpixel, convert, or save trigger the read.


2) Heap-based buffer overflow (CVE-ID: CVE-2026-59197)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: 8.8 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service and overwrite heap memory.

The vulnerability exists due to a heap-based buffer overflow in the ImageFilter.RankFilter API and ImagingExpand function when processing a very large odd filter size through public rank-filter classes. A remote attacker can supply a specially crafted filter size to cause a denial of service and overwrite heap memory.

The issue is reachable through documented public classes including RankFilter, MedianFilter, MinFilter, and MaxFilter. If the image is also attacker-supplied, the out-of-bounds value written past the allocation can be influenced by source image border pixels.


3) Out-of-bounds read (CVE-ID: CVE-2026-59198)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 8.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to disclose sensitive information.

The vulnerability exists due to an out-of-bounds read in the TGA RLE encoder when saving a mode "1" image through the public save API with TGA RLE compression. A remote attacker can save a specially crafted image to disclose sensitive information.

The issue can serialize adjacent process heap bytes into the generated TGA file, and a maximum-width single-row image can expose nearly the full adjacent heap window.


4) Heap-based buffer overflow (CVE-ID: CVE-2026-59199)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: 8.7 [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]


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

The vulnerability exists due to a heap-based buffer overflow in Pillow Image.paste(), Image.crop(), and Image.alpha_composite() when processing attacker-controlled image coordinates near signed 32-bit integer limits. A remote attacker can supply crafted coordinate values to cause a denial of service.

The direct Image.paste() path can copy attacker-controlled source pixel data into the out-of-bounds write, and the issue is reachable through documented public APIs without malformed image files.


5) Heap-based buffer overflow (CVE-ID: CVE-2026-59205)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: 8.7 [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]


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

The vulnerability exists due to a heap-based buffer overflow in ImageCmsTransform.apply() when processing a caller-supplied output image whose mode does not match the transform's declared output mode. A remote attacker can supply a crafted output image object to cause a denial of service.

The issue is reachable through Pillow's public ImageCms API, and the source image pixels can influence the bytes written out of bounds.


6) Path traversal (CVE-ID: CVE-2022-22815)

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVSSv4: 8.7 [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]


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.


7) Out-of-bounds read (CVE-ID: CVE-2022-22816)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 8.7 [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]


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.
