The remote NewStart CGSL host, running version MAIN 6.02, has glibc packages installed that are affected by multiple vulnerabilities:

  - An out-of-bounds write vulnerability was found in glibc before 2.31 when handling signal trampolines on     PowerPC. Specifically, the backtrace function did not properly check the array bounds when storing the     frame address, resulting in a denial of service or potential code execution. The highest threat from this     vulnerability is to system availability. (CVE-2020-1751)

  - A use-after-free vulnerability introduced in glibc upstream version 2.14 was found in the way the tilde     expansion was carried out. Directory paths containing an initial tilde followed by a valid username were     affected by this issue. A local attacker could exploit this flaw by creating a specially crafted path     that, when processed by the glob function, would potentially lead to arbitrary code execution. This was     fixed in version 2.32. (CVE-2020-1752)

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

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 :

  - An out-of-bounds write vulnerability was found in glibc     when handling signal trampolines on PowerPC. The     backtrace function did not properly check the array     bounds when storing the frame address resulting in a     denial of service or potential code execution. The     highest threat from this vulnerability is to system     availability.(CVE-2020-1751)

  - A signed comparison vulnerability was found in GNU libc     in the ARMv7 implementation of memcpy(). The flaw     affects the third argument to memcpy() that specifies     the number of bytes to copy. An underflow on the third     argument could lead to undefined behavior such as     out-of-bounds memory write and potentially remote code     execution.(CVE-2020-6096)

This update for glibc fixes the following issues :

CVE-2020-1752: Fixed a use after free in glob which could have allowed a local attacker to create a specially crafted path that, when processed by the glob function, could potentially have led to arbitrary code execution (bsc#1167631).

CVE-2020-1751: Fixed an array overflow in backtrace for PowerPC (bsc#1158996).

CVE-2020-10029: Fixed a stack-based buffer overflow during range reduction (bsc#1165784).

Use 'posix_spawn' on popen preventing crash caused by 'subprocess'.

  - 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)
