Package: wireguard Version: 1.0.20200319-1~bpo10+1 Severity: grave Hello wireguard package maintainer,
DSA 4667-1, a Linux security update released on 2020-04-28, includes a fix for CVE-2020-1749 that changes ipv6_stub to use ip6_dst_lookup_flow instead of ip6_dst_lookup. In wireguard-linux-compat/src/compat/compat.h, the following must be corrected such that ipv6_dst_lookup_flow is used for Debian linux kernel 4.19.0-9: 99 #if LINUX_VERSION_CODE < KERNEL_VERSION(3, 17, 0) && LINUX_VERSION_CODE >= KERNEL_VERSION(3, 16, 83) 100 #define ipv6_dst_lookup_flow(a, b, c, d) ipv6_dst_lookup_flow(b, c, d) 101 #elif (LINUX_VERSION_CODE < KERNEL_VERSION(5, 4, 5) && LINUX_VERSION_CODE >= KERNEL_VERSION(5, 4, 0)) || (LINUX_VERSION_CODE < KERNEL_VERSION(5, 3, 18) && !defined(ISRHEL82)) 102 #define ipv6_dst_lookup_flow(a, b, c, d) ipv6_dst_lookup(a, b, &dst, c) + (void *)0 ?: dst 103 #endif Otherwise, line 102 is used and the code fails to build from source.
