RHSA-2020_0566
Vulnerability from csaf_redhat - Published: 2020-02-20 22:18 - Updated: 2024-11-13 22:11A flaw was discovered in the way the python-pillow may allocate a large amount of memory or require a long time while processing specially crafted image files, possibly causing a denial of service. Applications that use the library to process untrusted files may be vulnerable to this flaw.
An out-of-bounds write flaw was discovered in python-pillow in the way SGI RLE images are decoded. An application that uses python-pillow to decode untrusted images may be vulnerable to this flaw, which can allow an attacker to crash the application or potentially execute code on the system.
A flaw was discovered in python-pillow does where it does not properly restrict operations within the bounds of a memory buffer when decoding PCX images. An application that uses python-pillow to decode untrusted images may be vulnerable to this flaw, which can allow an attacker to crash the application or potentially execute code on the system.
