CVE-2023-2804 severity moderate: SUSE including 24 source package names (libjpeg-turbo, libjpeg-turbo-3.0.1-77.1, …), 185 product×package rows across 50 product lines (SUSE CaaS Platform 4.0, SUSE Enterprise Storage 7, … (50 product lines)): Known Not Affected 166, Fixed 19.
A heap-based buffer overflow issue was discovered in libjpeg-turbo in h2v2_merged_upsample_internal() function of jdmrgext.c file. The vulnerability can only be exploited with 12-bit data precision for which the range of the sample data type exceeds the valid sample range, hence, an attacker could craft a 12-bit lossless JPEG image that contains out-of-range 12-bit samples. An application attempting to decompress such image using merged upsampling would lead to segmentation fault or buffer overflows, causing an application to crash.
