Descriptions
In libImaging/SgiRleDecode.c in Pillow through 7.0.0, a number of out-of-bounds reads exist in the parsing of SGI image files, a different issue than CVE-2020-5311.
En la biblioteca libImaging/SgiRleDecode.c en Pillow versiones hasta 7.0.0, se presentan múltiples lecturas fuera de límites en el análisis de archivos de imagen SGI, un problema diferente de CVE-2020-5311
An out-of-bounds read/write flaw was found in python-pillow, in the way SGI RLE images are decoded. An application that uses python-pillow to decode untrusted images may be vulnerable. This flaw allows an attacker to crash the application or potentially execute code on the system. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
USN-4430-1 fixed vulnerabilities in Pillow. This update provides the corresponding updates for Ubuntu 20.04 LTS. It was discovered that Pillow incorrectly handled certain image files. If a user or automated system were tricked into opening a specially-crafted image file, a remote attacker could possibly cause Pillow to crash, resulting in a denial of service. Various other issues were also addressed.
