>From the advisory: Jann Horn identified a problem in current versions of libseccomp where the library did not correctly generate 64-bit syscall argument comparisons using the arithmetic operators (LT, GT, LE, GE). Jann has done a search using codesearch.debian.net and it would appear that only systemd and Tor are using libseccomp in such a way as to trigger the bad code. In the case of systemd this appears to affect the socket address family and scheduling class filters. In the case of Tor it appears that the bad filters could impact the memory addresses passed to mprotect(2). The libseccomp v2.4.0 release fixes this problem, and should be a direct drop-in replacement for previous v2.x releases. https://www.openwall.com/lists/oss-security/2019/03/15/1 v2.4.0 adds a new scmp_api_level utility, so update 0001-remove-static.patch to match.
