In NTFS-3G before 2026.7.7, a heap buffer overflow exists in cat in ntfscat.c that allows an attacker to corrupt heap memory in the ntfscat binary by crafting a malicious NTFS image. The overflow is triggered by reading a file...

EUVD-2026-94357

In NTFS-3G before 2026.7.7, a heap buffer overflow exists in ntfsdecompress in compress.c that allows an attacker to corrupt one byte of heap memory in the SUID-root ntfs-3g binary by crafting a malicious NTFS image. The overflow is triggered by reading the special crafted file...

CVE-2026-42618

In NTFS-3G before 2026.7.7, a heap buffer overflow exists in ntfsdecompress in compress.c that allows an attacker to corrupt one byte of heap memory in the SUID-root ntfs-3g binary by crafting a malicious NTFS image. The overflow is triggered by reading the special crafted file...

CVE-2026-106066: Improper Restriction of Operations within the Bounds of a Memory Buffer

A heap-based buffer overflow was found in GIMP’s raw data export plug-in. When exporting very large images, gmalloc sizing based on overflowing width height bytes-per-pixel can allocate far less memory than GEGL reads or writes during export, following integer overflow...

CVE-2026-106065: Improper Restriction of Operations within the Bounds of a Memory Buffer

A heap-based buffer overflow was found in GIMP’s PCX export plug-in. For images with extremely large width and height, buffer allocation uses overflowing 32-bit width height arithmetic while subsequent GEGL operations use the full extent, after integer overflow in size calculation...

PT-2026-107530

A heap-based buffer overflow was found in GIMP’s GIF export plug-in. Exporting an image with very large width and height can cause 32-bit overflow when computing the pixel buffer size. The plug-in allocates a buffer based on the wrapped value while GEGL writes using the true image extent, rooted ...
