GHSA-782X-JH29-9MF7 ImageMagick: MSL image stack index may fail to refresh, leading to leaked images

Sometimes msl.c fails to update the stack index, so an image is stored in the wrong slot and never freed on error, causing leaks. ==841485==ERROR: LeakSanitizer: detected memory leaks Direct leak of 13512 bytes in 1 objects allocated from: 0 0x7ff330759887 in interceptormalloc...

ImageMagick has Use After Free in MSLStartElement in "coders/msl.c"

A crafted MSL script triggers a heap-use-after-free. The operation element handler replaces and frees the image while the parser continues reading from it, leading to a UAF in ReadBlobString during further parsing...

GHSA-72HF-FJ62-W6J4 ImageMagick: Stack buffer overflow in FTXT reader via oversized integer field

Summary A stack-based buffer overflow exists in the ImageMagick FTXT image reader. A crafted FTXT file can cause out-of-bounds writes on the stack, leading to a crash. ================================================================= ==3537074==ERROR: AddressSanitizer: stack-buffer-overflow on...

GHSA-XWC6-V6G8-PW2H ImageMagick's Security Policy Bypass through config/policy-secure.xml via "fd handler" leads to stdin/stdout access

The shipped “secure” security policy includes a rule intended to prevent reading/writing from standard streams: xml However, ImageMagick also supports fd: pseudo-filenames e.g., fd:0, fd:1. This path form is not blocked by the secure policy templates, and therefore bypasses the protection goal of...

GHSA-8JVJ-P28H-9GM7 ImageMagick: Policy bypass through path traversal allows reading restricted content despite secured policy

ImageMagick’s path security policy is enforced on the raw filename string before the filesystem resolves it. As a result, a policy rule such as /etc/ can be bypassed by a path traversal. The OS resolves the traversal and opens the sensitive file, but the policy matcher only sees the unnormalized...

ImageMagick has Global Buffer Overflow (OOB Read) via Negative Pixel Index in UIL and XPM Writer

The UIL and XPM image encoder do not validate the pixel index value returned by GetPixelIndex before using it as an array subscript. In HDRI builds, Quantum is a floating-point type, so pixel index values can be negative. An attacker can craft an image with negative pixel index values to trigger ...

ImageMagick: Heap overflow in sun decoder on 32-bit systems may result in out of bounds write

An Integer Overflow vulnerability exists in the sun decoder. On 32-bit systems/builds, a carefully crafted image can lead to an out of bounds heap write. ================================================================= ==1967675==ERROR: AddressSanitizer: heap-buffer-overflow on address 0xf190b50...

GHSA-543G-8GRM-9CW6 ImageMagick has Division-by-Zero in YUV sampling factor validation, which leads to crash

A logic error in YUV sampling factor validation allows an invalid sampling factor to bypass checks and trigger a division-by-zero during image loading, resulting in a reliable denial-of-service. coders/yuv.c:210:47: runtime error: division by zero AddressSanitizer:DEADLYSIGNAL...

GHSA-P863-5FGM-RGQ4 ImageMagick has NULL Pointer Dereference in ClonePixelCacheRepository via crafted image

A NULL pointer dereference in ClonePixelCacheRepository allows a remote attacker to crash any application linked against ImageMagick by supplying a crafted image file, resulting in Denial of Service. AddressSanitizer:DEADLYSIGNAL =================================================================...

GHSA-RW6C-XP26-225V ImageMagick: Code Injection via PostScript header in ps coders

The ps encoders, responsible for writing PostScript files, fails to sanitize the input before writing it into the PostScript header. An attacker can provide a malicious file and inject arbitrary PostScript code. When the resulting file is processed by a printer or a viewer like Ghostscript, the...

GHSA-G2PR-QXJG-7R2W ImageMagick has memory leak of watermark Image object in ReadSTEGANOImage on multiple error/early-return paths

Summary In ReadSTEGANOImage coders/stegano.c, the watermark Image object is not freed on three early-return paths, resulting in a definite memory leak 13.5KB+ per invocation that can be exploited for denial of service. Direct leak of 13512 bytes in 1 objects allocated from: 0 0x7f5c11e27887 in...

ImageMagick has heap-buffer-overflow via signed integer overflow in WriteUHDRImage when writing UHDR images with large dimensions

WriteUHDRImage in coders/uhdr.c uses int arithmetic to compute the pixel buffer size. When image dimensions are large, the multiplication overflows 32-bit int, causing an undersized heap allocation followed by an out-of-bounds write. This can crash the process or potentially lead to an out of...
