A crafted FTP PASV/EPSV response with an over-long port or address octet wraps the value, so the helper configures the data connection with a truncated port/address.</p> <p>The netfilter conntrack FTP helper had the same defect, fixed in commit 2b413fc689ba (&#34;netfilter: nf_conntrack_ftp: avoid u16 overflows&#34;). Apply the equivalent fix here: widen the port accumulator to u32 and reject values above 65535, and reject address octets above 255.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>ipvs: fix integer overflow in ftp helper port/address parsing</p> <p>ip_vs_ftp_get_addrport() accumulates decimal digits into a __u16 (hport) and into unsigned char (p[]) without checking for overflow.
