Descripción técnica

Pillow is a Python imaging library. Prior to 13.0.0, Pillow can double free image memory when ImagingScaleAffine encounters a selective allocation failure. The affected fast path handles Transform.EXTENT or pure scale-and-translate Transform.AFFINE operations with the default NEAREST resampling. The output image allocation must succeed while the additional per-column lookup allocation fails, after which the error path deletes image storage that later cleanup releases again. An attacker who can drive such a large Image.transform() operation under memory pressure may trigger the failure. This can crash the process and may corrupt memory. This issue is fixed in version 13.0.0.

——0Pillow is a Python imaging library. From 11.3.0 until 13.0.0, Pillow has a heap use-after-free when libtiff rejects a tag while encoding TIFF data to an in-memory buffer. When an application saves attacker-influenced TIFF tags to BytesIO, libtiff can reject a tag during encoding in ImagingLibTiffEncode; the error path then frees the output buffer without closing or clearing the TIFF handle, and later cleanup flushes through the write callback into freed memory, which can crash the process and may enable code execution. This issue is fixed in version 13.0.0.14h CVE-2026-1122617.8 ALT

——0A flaw was found in GIMP. Opening a crafted XCF that selects a path and then fails to load that path can cause a use-after-free in the main process, leading to a crash and potentially arbitrary code execution.14h CVE-2026-1122587.8 ALT

——0A flaw was found in GIMP. The XCF loader can leave a dangling pointer in the linked-channels list when a linked channel is later destroyed via a selection property. Opening a crafted XCF file can cause a use-after-free in the main GIMP process, leading to a crash and potentially arbitrary code execution.14h CVE-2026-110686—

——0Cpanel::JSON::XS versions before 4.80 for Perl use freed filter callbacks when a filter removes itself during decoding in decode_hv. A decode copies the parser's filter_json_object and filter_json_single_key_object callbacks without taking references to them. A filter callback that removes the last single-key filter frees the callback table while the decode in progress still uses it. The next object is dispatched through freed memory and can crash the process.15h CVE-2026-110681—

——0Cpanel::JSON::XS versions before 4.80 for Perl use the parent interpreter's scalars from a parser object cloned into a new ithread. A parser object holds its callbacks and its incremental parse buffer as raw scalar pointers. When a thread is created, these are copied into the new interpreter unchanged, so the child's parser uses, and later frees, scalars that belong to the parent and may already have been freed there. A parser created before a thread starts and used inside it can call freed callbacks, corrupt reference counts and crash the process.15h CVE-2026-1120945.5 MED

——2A security vulnerability has been detected in michaelrsweet mxml 4.0.5/4.0.6. This affects the function mxml_load_data of the file mxml-file.c. The manipulation leads to use after free. The attack is possible to be carried out remotely. The exploit has been disclosed publicly and may be used. The project was informed of the problem early through an issue report but has not responded yet.18h
