EulerOS 2.0 SP5 : glibc (EulerOS-SA-2021-2496)

high Nessus Plugin ID 153747

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the glibc packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- sysdeps/i386/ldbl2mpn.c in the GNU C Library (aka glibc or libc6) before 2.23 on x86 targets has a stack- based buffer overflow if the input to any of the printf family of functions is an 80-bit long double with a non-canonical bit pattern, as seen when passing a \x00\x04\x00\x00\x00\x00\x00\x00\x00\x04 value to sprintf. NOTE: the issue does not affect glibc by default in 2016 or later (i.e., 2.23 or later) because of commits made in 2015 for inlining of C99 math functions through use of GCC built-ins. In other words, the reference to 2.23 is intentional despite the mention of 'Fixed for glibc 2.33' in the 26649 reference.
(CVE-2020-29573)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected glibc packages.
