medium Tenable Self-Hosted Container Security Plugin ID 460754

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-77014)
