In ImageMagick versions prior to 7.1.2-7 and 6.9.13-32, an integer overflow vulnerability exists in the BMP decoder on 32-bit systems. The vulnerability occurs in coders/bmp.c when calculating the extent value by multiplying image columns by bits per pixel. On 32-bit systems with size_t of 4 bytes, a malicious BMP file with specific dimensions can cause this multiplication to overflow and wrap to zero. The overflow check added to address CVE-2025-57803 is placed after the overflow occurs, making it ineffective. A specially crafted 58-byte BMP file with width set to 536,870,912 and 32 bits per pixel can trigger this overflow, causing the bytes_per_line calculation to become zero. This vulnerability only affects 32-bit builds of ImageMagick where default resource limits for width, height, and area have been manually increased beyond their defaults. 64-bit systems with size_t of 8 bytes are not vulnerable, and systems using default ImageMagick resource limits are not vulnerable. The vulnerability is fixed in versions 7.1.2-7 and 6.9.13-32."},{"lang":"es","value":"ImageMagick es una suite de software de código abierto para mostrar, convertir y editar archivos de imagen ráster. En las versiones de ImageMagick anteriores a la 7.1.2-7 y 6.9.13-32, existe una vulnerabilidad de desbordamiento de entero en el decodificador BMP en sistemas de 32 bits. La vulnerabilidad ocurre en coders/bmp.c al calcular el valor de extensión multiplicando las columnas de la imagen por los bits por píxel. En sistemas de 32 bits con size_t de 4 bytes, un archivo BMP malicioso con dimensiones específicas puede causar que esta multiplicación se desborde y se ajuste a cero. La comprobación de desbordamiento añadida para abordar CVE-2025-57803 se coloca después de que ocurre el desbordamiento, lo que la hace ineficaz. Un archivo BMP de 58 bytes especialmente diseñado con un ancho establecido en 536,870,912 y 32 bits por píxel puede desencadenar este desbordamiento, haciendo que el cálculo de bytes_per_line se convierta en cero. Esta vulnerabilidad solo afecta a las compilaciones de 32 bits de ImageMagick donde los límites de recursos predeterminados para ancho, alto y área se han aumentado manualmente más allá de sus valores predeterminados. Los sistemas de 64 bits con size_t de 8 bytes no son vulnerables, y los sistemas que utilizan los límites de recursos predeterminados de ImageMagick no son vulnerables. La vulnerabilidad está corregida en las versiones 7.1.2-7 y 6.9.13-32."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"ImageMagick","product":"ImageMagick","versions":[{"version":"< 6.9.13-32","status":"affected"},{"version":">= 7.0.0-0, < 7.1.2-7","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":5.9,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":2.2,"impactScore":3.6},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":3.6}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2025-10-17T17:05:36.358600Z","id":"CVE-2025-62171","options":[{"exploitation":"poc"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-190"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:imagemagick:imagemagick:*:*:*:*:*:*:*:*","versionEndExcluding":"6.9.13-32","matchCriteriaId":"EB78F6C2-7C33-4A0A-A093-6A26A8B9C3BF"},{"vulnerable":true,"criteria":"cpe:2.3:a:imagemagick:imagemagick:*:*:*:*:*:*:*:*","versionStartIncluding":"7.0.0-0","versionEndExcluding":"7.1.2-7","matchCriteriaId":"5F3152BE-0219-45B9-940F-86EED0E01510"}]}]}],"references":[{"url":"https://github.com/ImageMagick/ImageMagick/commit/cea1693e2ded51b4cc91c70c54096cbed1691c00","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-9pp9-cfwx-54rm","source":"security-advisories@github.com","tags":["Exploit","Vendor Advisory"]},{"url":"https://lists.debian.org/debian-lts-announce/2025/10/msg00019.html","source":"af854a3a-2127-422b-91ae-364da2661108"}]}
