CVSS: 5.5EPSS: 0%CPEs: 1EXPL: 0CVE-2021-46822 – libjpeg-turbo: heap buffer overflow in get_word_rgb_row() in rdppm.c
https://notcve.org/view.php?id=CVE-2021-46822
The PPM reader in libjpeg-turbo through 2.0.90 mishandles use of tjLoadImage for loading a 16-bit binary PPM file into a grayscale buffer and loading a 16-bit binary PGM file into an RGB buffer. This is related to a heap-based buffer overflow in the get_word_rgb_row function in rdppm.c. El lector PPM en libjpeg-turbo versiones hasta 2.0.90, maneja inapropiadamente el uso de tjLoadImage para cargar un archivo PPM binario de 16 bits en un búfer de escala de grises y cargar un archivo PGM binario de 16 bits en un búfer RGB. Esto está relacionado con un desbordamiento del búfer en la región heap de la memoria en la función get_word_rgb_row en rdppm.c A heap-based buffer overflow vulnerability was found in libjpeg-turbo in the get_word_rgb_row() function in rdppm.c. The flaw occurs when the PPM reader in libjpeg-turbo mishandles use of the tjLoadImage() function for loading a 16-bit binary PPM file into a grayscale uncompressed image buffer and then loading a 16-bit binary PGM file into an RGB uncompressed image buffer. • https://exchange.xforce.ibmcloud.com/vulnerabilities/221567 https://github.com/libjpeg-turbo/libjpeg-turbo/commit/f35fd27ec641c42d6b115bfa595e483ec58188d2 https://access.redhat.com/security/cve/CVE-2021-46822 https://bugzilla.redhat.com/show_bug.cgi?id=2100044 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
CVSS: 8.8EPSS: 0%CPEs: 1EXPL: 1CVE-2020-17541 – libjpeg-turbo: Stack-based buffer overflow in the "transform" component
https://notcve.org/view.php?id=CVE-2020-17541
Libjpeg-turbo all version have a stack-based buffer overflow in the "transform" component. A remote attacker can send a malformed jpeg file to the service and cause arbitrary code execution or denial of service of the target service. Libjpeg-turbo todas las versiones presentan un desbordamiento de búfer en la región stack de la memoria en el componente "transform". Un atacante remoto puede enviar un archivo jpeg malformado al servicio y causar una ejecución de código arbitrario o una denegación del servicio objetivo A stack-based buffer overflow flaw was found in libjpeg-turbo library in the tranform component. An attacker may use this flaw to input a malicious image file to an application utilizing this library, leading to arbitrary code execution. • https://cwe.mitre.org/data/definitions/121.html https://github.com/libjpeg-turbo/libjpeg-turbo/issues/392 https://access.redhat.com/security/cve/CVE-2020-17541 https://bugzilla.redhat.com/show_bug.cgi?id=1968036 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •

The tjLoadImage function in libjpeg-turbo 2.0.1 has an integer overflow with a resultant heap-based buffer overflow via a BMP image because multiplication of pitch and height is mishandled, as demonstrated by tjbench. La función tjLoadImage en libjpeg-turbo en 2.0.1 tiene un desbordamiento de enteros con un desbordamiento de búfer basado en memoria dinámica (heap) resultante mediante una imagen BMP. Esto se debe a que se gestiona de manera incorrecta la multiplicación del pitch y la altura, tal y como queda demostrado con tjbench. • https://github.com/libjpeg-turbo/libjpeg-turbo/issues/304 https://usn.ubuntu.com/4190-1 • CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •
