UBUNTU-CVE-2019-9893

libseccomp before 2.4.0 did not correctly generate 64-bit syscall argument comparisons using the arithmetic operators LT, GT, LE, GE, which might able to lead to bypassing seccomp filters and potential privilege escalations...

CVE-2019-7303

A vulnerability in the seccomp filters of Canonical snapd before version 2.37.4 allows a strict mode snap to insert characters into a terminal on a 64-bit host. The seccomp rules were generated to match 64-bit ioctl2 commands on a 64-bit platform; however, the Linux kernel only uses the lower 32...

libseccomp 2.4.0 - Incorrect Compilation of Arithmetic Comparisons

libseccomp 2.4.0 - Incorrect Compilation of Arithmetic Comparisons When libseccomp compiles filters for 64-bit systems, it needs to split 64-bit comparisons into 32-bit comparisons because classic BPF can't operate on 64-bit values directly. libseccomp offers both bitwise comparisons NE, EQ,...

libseccomp < 2.4.0 - Incorrect Compilation of Arithmetic Comparisons Exploit

When libseccomp compiles filters for 64-bit systems, it needs to split 64-bit comparisons into 32-bit comparisons because classic BPF can't operate on 64-bit values directly. libseccomp offers both bitwise comparisons NE, EQ, MASKEDEQ and arithmetic comparisons LT, LE, GE, GT. Bitwise comparisons...
