USN-8999-1: Pillow vulnerabilities

It was discovered that Pillow incorrectly handled map stride values when loading certain McIdas AREA images. An attacker could possibly use this issue to obtain sensitive information or cause a denial of service. (CVE-2026-54058)

It was discovered that Pillow did not properly check for decompression bombs when processing font files. An attacker could possibly use this issue to cause Pillow to consume excessive memory, resulting in a denial of service. (CVE-2026-54059, CVE-2026-54060, CVE-2026-55379)

It was discovered that Pillow did not properly check for decompression bombs when loading GD image files. An attacker could possibly use this issue to cause Pillow to consume excessive memory, resulting in a denial of service. (CVE-2026-55380)

It was discovered that Pillow incorrectly validated filter sizes in the rank filter implementation. An attacker could possibly use this issue to cause Pillow to crash or execute arbitrary code. (CVE-2026-59197)

It was discovered that Pillow incorrectly handled image coordinate calculations. An attacker could possibly use this issue to cause Pillow to crash. (CVE-2026-59199)

It was discovered that Pillow did not properly limit the size of decompressed PDF stream data. An attacker could possibly use this issue to cause Pillow to consume excessive memory, resulting in a denial of service. (CVE-2026-59200)

It was discovered that Pillow incorrectly parsed EPS files containing a negative byte count in the BeginBinary directive. An attacker could possibly use this issue to cause Pillow to hang, resulting in a denial of service. This issue only affected Ubuntu 26.04 LTS. (CVE-2026-59203)

It was discovered that Pillow incorrectly accumulated JPEG2000 tile component widths. An attacker could possibly use this issue to cause Pillow to consume excessive memory, resulting in a denial of service. (CVE-2026-59204)

It was discovered that Pillow incorrectly validated image mode compatibility in color management transforms. An attacker could possibly use this issue to cause Pillow to crash or execute arbitrary code. (CVE-2026-59205)
