This updated addresses a minor security vulnerability in the Sun RPC client (CVE-2016-4429), increases compatibility with GCC 6, and addresses a problem which caused `fork` to crash when `BIND_NOW` was used for linking shared objects.

Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

It was discovered that libtiprc, a transport-independent RPC library, could be used for a denial of service or possibly unspecified other impact by a stack-based buffer overflow due to a flood of crafted ICMP and UDP packets.

For Debian 8 'Jessie', this problem has been fixed in version 0.2.5-1+deb8u3.

We recommend that you upgrade your libtirpc packages.

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

  - Stack-based buffer overflow in the clntudp_call     function in sunrpc/clnt_udp.c in the GNU C Library (aka     glibc or libc6) allows remote servers to cause a denial     of service (crash) or possibly unspecified other impact     via a flood of crafted ICMP and UDP     packets.(CVE-2016-4429)

  - Integer overflow in the strxfrm function in the GNU C     Library (aka glibc or libc6) before 2.21 allows     context-dependent attackers to cause a denial of     service (crash) or possibly execute arbitrary code via     a long string, which triggers a stack-based buffer     overflow.(CVE-2015-8982)

  - The posix_spawn_file_actions_addopen function in glibc     before 2.20 does not copy its path argument in     accordance with the POSIX specification, which allows     context-dependent attackers to trigger use-after-free     vulnerabilities.(CVE-2014-4043)

An update of the glibc package has been released.

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

  - elf/dl-load.c in the GNU C Library (aka glibc or libc6)     2.19 through 2.26 mishandles RPATH and RUNPATH     containing $ORIGIN for a privileged (setuid or     AT_SECURE) program, which allows local users to gain     privileges via a Trojan horse library in the current     working directory, related to the fillin_rpath and     decompose_rpath functions. This is associated with     misinterpretion of an empty RPATH/RUNPATH token as the     './' directory. NOTE: this configuration of     RPATH/RUNPATH for a privileged program is apparently     very uncommon most likely, no such program is shipped     with any common Linux distribution(CVE-2017-16997)

  - Stack-based buffer overflow in the clntudp_call     function in sunrpc/clnt_udp.c in the GNU C Library (aka     glibc or libc6) allows remote servers to cause a denial     of service (crash) or possibly unspecified other impact     via a flood of crafted ICMP and UDP     packets.(CVE-2016-4429)

  - Integer overflow in the strxfrm function in the GNU C     Library (aka glibc or libc6) before 2.21 allows     context-dependent attackers to cause a denial of     service (crash) or possibly execute arbitrary code via     a long string, which triggers a stack-based buffer     overflow.(CVE-2015-8982)

  - A buffer overflow has been discovered in the GNU C     Library (aka glibc or libc6) in the
    __mempcpy_avx512_no_vzeroupper function when particular     conditions are met. An attacker could use this     vulnerability to cause a denial of service or     potentially execute code.(CVE-2018-11237)

  - The posix_spawn_file_actions_addopen function in glibc     before 2.20 does not copy its path argument in     accordance with the POSIX specification, which allows     context-dependent attackers to trigger use-after-free     vulnerabilities.(CVE-2014-4043)

  - res_query in libresolv in glibc before 2.25 allows     remote attackers to cause a denial of service (NULL     pointer dereference and process crash).(CVE-2015-5180)

  - A buffer overflow has been discovered in the GNU C     Library (aka glibc or libc6) in the
    __mempcpy_avx512_no_vzeroupper function when particular     conditions are met. An attacker could use this     vulnerability to cause a denial of service or     potentially execute code.(CVE-2018-11237)

  - In the GNU C Library (aka glibc or libc6) through 2.29,     proceed_next_node in posix/regexec.c has a heap-based     buffer over-read via an attempted case-insensitive     regular-expression match.(CVE-2019-9169)

  - The iconv program in the GNU C Library (aka glibc or     libc6) 2.25 and earlier, when invoked with the -c     option, enters an infinite loop when processing invalid     multi-byte input sequences, leading to a denial of     service.(CVE-2016-10228)

  - The DNS stub resolver in the GNU C Library (aka glibc     or libc6) before version 2.26, when EDNS support is     enabled, will solicit large UDP responses from name     servers, potentially simplifying off-path DNS spoofing     attacks due to IP fragmentation.(CVE-2017-12132)
