Medium [CVE-2026-77014] Libsoup: libsoup: integer truncation in sort_ranges comparator causes silent omission of http range responses
CVE-2026-77014Source published Source updated
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. A remote attacker can exploit this to cause the server to silently omit requested byte ranges from responses. Exploitation requires the server to be serving resources larger than approximately 2 GB, which limits real-world impact. Red Hat severity: Moderate — CVSS 5.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N). Weakness: CWE-197. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise…
