NVD Description

Note: Versions mentioned in the description apply only to the upstream libsoup-2_4-1 package and not the libsoup-2_4-1 package as distributed by SLES. See How to fix? for SLES:15.6 relevant fixed versions and status.

A flaw was found in libsoup's SoupServer HTTP Range header processing. The sort_ranges() comparator in soup-message-headers.c truncates a 64-bit subtraction result to 32-bit int, flipping the sign for range offsets differing by more than INT_MAX. This causes silent omission of requested byte ranges from HTTP 206 Partial Content responses on resources larger than approximately 2 GB.
