EulerOS Virtualization for ARM 64 3.0.6.0 : glibc (EulerOS-SA-2021-1537)

high Nessus Plugin ID 147065

Synopsis

The remote EulerOS Virtualization for ARM 64 host is missing multiple security updates.

Description

According to the versions of the glibc packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

 - A flaw was found in glibc. If an attacker provides the iconv function with invalid multi-byte input sequences in IBM1364, IBM1371, IBM1388, IBM1390, IBM1399 encodings, it fails to advance the input state, which could lead to an infinite loop in applications, resulting in a denial of service.(CVE-2020-27618)

 - 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)

 - The iconv function in the GNU C Library (aka glibc or libc6) 2.30 to 2.32, when converting UCS4 text containing an irreversible character, fails an assertion in the code path and aborts the program, potentially resulting in a denial of service.(CVE-2020-29562)

 - The iconv feature in the GNU C Library (aka glibc or libc6) through 2.32, when processing invalid multi-byte input sequences in the EUC-KR encoding, may have a buffer over-read.(CVE-2019-25013)

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.
