The version of F5 Networks BIG-IP installed on the remote host is prior to 14.1.4.3 / 15.1.4 / 16.0.1.2 / 16.1.0. It is, therefore, affected by a vulnerability as referenced in the K38481791 advisory.

  • The GNU C Library (aka glibc or libc6) before 2.32 could overflow an on-stack buffer during range reduction if an input to an 80-bit long double function contains a non-canonical bit pattern, a seen when passing a 0x5d414141414141410000 value to sinl on x86 targets. This is related to sysdeps/ieee754/ldbl-96/e_rem_pio2l.c. (CVE-2020-10029)

Note that Nessus has not tested for this issue but has instead relied only on the applicationโ€™s self-reported version number.
