ImageSharp: TIFF CCITT T6 encoder writes beyond an undersized output buffer

Summary The TIFF CCITT Group 4 T6 encoder writes beyond its logical compressed-data buffer when encoding a 1-bit image. A valid 1×1 Group 4 TIFF decoded and re-encoded with the default TiffEncoder terminates the process with an unhandled exception. Affected package and versions - Package:...

Excelize ColumnNameToNumber: int64 overflow yields an out-of-domain coordinate with nil error, causing negative slice index panic on r="0" rows

Summary ColumnNameToNumber lib.go:220-237 accumulates the bijective base-26 value of a column name in an int64 with only an upper-bound check col MaxColumns applied after the loop and no overflow detection. A 14-letter column name whose true value is 3·2⁶⁴ — e.g. VGWQHXLSDVIKWV — wraps to col = 0...

CVE-2026-46572

A flaw was found in ntfs-3g. This vulnerability allows a local attacker to achieve privilege escalation or cause a denial of service DoS by corrupting system memory. By providing a specially crafted NTFS filesystem image and creating a file within a malicious directory, an attacker can trigger a...

CVE-2026-46569

A flaw was found in NTFS-3G. A heap-based buffer overflow allows a local attacker to potentially achieve privilege escalation by supplying a specially crafted NTFS file system image. When extending a directory on the malicious image, such as by creating a file, memory within the privileged utilit...

CVE-2026-42617

A flaw was found in NTFS-3G. A heap-based buffer overflow occurs when expanding a directory on a specially crafted NTFS filesystem image, such as during file creation.
