Description

This security bulletin contains information about 1 vulnerability.


1) Off-by-one (CVE-ID: CVE-2026-45232)

CWE-ID: CWE-193 - Off-by-one Error

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to an off-by-one out-of-bounds stack write in establish_proxy_connection() in socket.c when processing the first response line from an HTTP CONNECT proxy. A remote attacker can return a pathological proxy response line without a newline terminator to cause a denial of service.

The issue is reachable only on the client side when RSYNC_PROXY is set, and the written byte is a fixed \0.
