Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 29 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

Description

# Heap Buffer Overflow in InterpretImageFilename ## Summary A heap buffer overflow was identified in the `InterpretImageFilename` function of ImageMagick. The issue stems from an off-by-one error that causes out-of-bounds memory access when processing format strings containing consecutive percent signs (`%%`). ## Environment - **OS**: Arch Linux (Linux gmkhost 6.14.2-arch1-1 # 1 SMP PREEMPT_DYNAMIC Thu, 10 Apr 2025 18:43:59 +0000 x86_64 GNU/Linux (GNU libc) 2.41) - **Architecture**: x86_64 - **Compiler**: gcc (GCC) 15.1.1 20250425 ## Reproduction ### Build Instructions ```bash # Clone the repository git clone https://github.com/ImageMagick/ImageMagick.git cd ImageMagick git reset --hard 8fff9b4f44d2e8b5cae2bd6db70930a144d15f12 # Build with AddressSanitizer export CFLAGS="-fsanitize=address -g -O1" export CXXFLAGS="-fsanitize=address -g -O1" export LDFLAGS="-fsanitizer=address" ./configure make # Set library path and trigger the crash export LD_LIBRARY_PATH="$(pwd)/MagickWand/.libs:$(pwd)/MagickCore/.libs:$LD_LIBRARY_PATH" ./utilities/.libs/magick %% a ``` ### Minimum Trigger ```bash ./utilities/.libs/magick %% [any_output_filename] ``` ## Crash Analysis ### AddressSanitizer Output ``` $ ./utilities/.libs/magick %% a ================================================================= ==2227694==ERROR: AddressSanitizer: heap-buffer-overflow on address 0x7037f99e3ad3 at pc 0x741801e81a17 bp 0x7ffd22fa4e00 sp 0x7ffd22fa45b8 READ of size 1 at 0x7037f99e3ad3 thread T0 #0 0x741801e81a16 in strchr /usr/src/debug/gcc/gcc/libsanitizer/sanitizer_common/sanitizer_common_interceptors.inc:746 #1 0x7418013b4f06 in InterpretImageFilename MagickCore/image.c:1674 #2 0x7418012826a3 in ReadImages MagickCore/constitute.c:1040 #3 0x741800e4696b in CLINoImageOperator MagickWand/operation.c:4959 #4 0x741800e64de7 in CLIOption MagickWand/operation.c:5473 #5 0x741800d92edf in ProcessCommandOptions MagickWand/magick-cli.c:653 #6 0x741800d94816 in MagickImageCommand MagickWand/magick-cli.c:1392 #7 0x741800d913e4 in MagickCommandGenesis MagickWand/magick-cli.c:177 #8 0x5ef7a3546638 in MagickMain utilities/magick.c:162 #9 0x5ef7a3546872 in main utilities/magick.c:193 #10 0x7417ff53f6b4 (/usr/lib/libc.so.6+0x276b4) (BuildId: 468e3585c794491a48ea75fceb9e4d6b1464fc35) #11 0x7417ff53f768 in __libc_start_main (/usr/lib/libc.so.6+0x27768) (BuildId: 468e3585c794491a48ea75fceb9e4d6b1464fc35) #12 0x5ef7a3546204 in _start (/home/kforfk/workspace/fuzz_analysis/saigen/ImageMagick/utilities/.libs/magick+0x2204) (BuildId: 96677b60628cf297eaedb3eb17b87000d29403f2) 0x7037f99e3ad3 is located 0 bytes after 3-byte region [0x7037f99e3ad0,0x7037f99e3ad3) allocated by thread T0 here: #0 0x741801f20e15 in malloc /usr/src/debug/gcc/gcc/libsanitizer/asan/asan_malloc_linux.cpp:67 #1 0x7418013e86bc in AcquireMagickMemory MagickCore/memory.c:559 SUMMARY: AddressSanitizer: heap-buffer-overflow MagickCore/image.c:1674 in InterpretImageFilename Shadow bytes around the buggy address: 0x7037f99e3800: fa fa 07 fa fa fa 00 fa fa fa fd fa fa fa fd fa 0x7037f99e3880: fa fa 07 fa fa fa 00 fa fa fa fd fa fa fa fd fa 0x7037f99e3900: fa fa 07 fa fa fa 00 fa fa fa fd fa fa fa fd fa 0x7037f99e3980: fa fa 07 fa fa fa 00 fa fa fa fd fa fa fa fd fa 0x7037f99e3a00: fa fa 07 fa fa fa fd fa fa fa fd fa fa fa 00 04 =>0x7037f99e3a80: fa fa 00 04 fa fa 00 00 fa fa[03]fa fa fa 03 fa 0x7037f99e3b00: fa fa 00 01 fa fa fa fa fa fa fa fa fa fa fa fa 0x7037f99e3b80: fa fa fa fa fa fa fa fa fa fa fa fa fa fa fa fa 0x7037f99e3c00: fa fa fa fa fa fa fa fa fa fa fa fa fa fa fa fa 0x7037f99e3c80: fa fa fa fa fa fa fa fa fa fa fa fa fa fa fa fa 0x7037f99e3d00: fa fa fa fa fa fa fa fa fa fa fa fa fa fa fa fa Shadow byte legend (one shadow byte represents 8 application bytes): Addressable: 00 Partially addressable: 01 02 03 04 05 06 07 Heap left redzone: fa Freed heap region: fd Stack left redzone: f1 Stack mid redzone: f2 Stack right redzone: f3 Stack after return: f5 Stack use after scope: f8 Global redzone: f9 Global init order: f6 Poisoned by user: f7 Container overflow: fc Array cookie: ac Intra object redzone: bb ASan internal: fe Left alloca redzone: ca Right alloca redzone: cb ==2227694==ABORTING ``` ## Root Cause Analysis The first command line argument is interpreted as `MagickImageCommand`: https://github.com/ImageMagick/ImageMagick/blob/8fff9b4f44d2e8b5cae2bd6db70930a144d15f12/utilities/magick.c#L83 ```c const CommandInfo MagickCommands[] = { MagickCommandSize("magick", MagickFalse, MagickImageCommand), ``` It is invoked here: https://github.com/ImageMagick/ImageMagick/blob/8fff9b4f44d2e8b5cae2bd6db70930a144d15f12/MagickWand/magick-cli.c#L220 ```c status=command(image_info,argc,argv,&text,exception); ``` The execution then follows this path: - https://gi

CWE-125Out-of-bounds Read (opens in a new tab)
Base weaknessCWE Top 25 (2025): #8
The product reads data past the end, or before the beginning, of the intended buffer.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
Architecture and Design · Language Selection
Use a language that provides appropriate memory abstractions.

Base weakness
A product calculates or uses an incorrect maximum or minimum value that is 1 more, or 1 less, than the correct value.
Implementation
When copying character arrays or using character manipulation methods, the correct size parameter must be used to account for the null terminator that needs to be added at the end of the array.
