F5 Networks BIG-IP : glibc vulnerability (K38481791)

medium Nessus Plugin ID 150462
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

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)

Impact

Specially crafted values passed to certain glibc functions may create a stack-based overflow, potentially leading to an unexpected process restart.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K38481791.
