Nutanix AHV : Multiple Vulnerabilities (NXSA-AHV-20201105.1082)

high Nessus Plugin ID 164563

Synopsis

The Nutanix AHV host is affected by multiple vulnerabilities .

Description

The version of AHV installed on the remote host is prior to 20201105.1082. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20201105.1082 advisory.

- Perl before 5.30.3 has an integer overflow related to mishandling of a PL_regkind[OP(n)] == NOTHING situation. A crafted regular expression could lead to malformed bytecode with a possibility of instruction injection. (CVE-2020-10878)

- Perl before 5.30.3 on 32-bit platforms allows a heap-based buffer overflow because nested regular expression quantifiers have an integer overflow. (CVE-2020-10543)

- regcomp.c in Perl before 5.30.3 allows a buffer overflow via a crafted regular expression because of recursive S_study_chunk calls. (CVE-2020-12723)

- 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)

- 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 these issues but has instead relied only on the application's self-reported version number.

Solution

Update the Nutanix AHV software to the recommended version. Before upgrading: if this cluster is registered with Prism Central, ensure that Prism Central has been upgraded first to a compatible version. Refer to the Software Product Interoperability page on the Nutanix portal.
