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

  - In the GNU C Library (aka glibc or libc6) through 2.28,     the getaddrinfo function would successfully parse a     string that contained an IPv4 address followed by     whitespace and arbitrary characters, which could lead     applications to incorrectly assume that it had parsed a     valid string, without the possibility of embedded HTTP     headers or other potentially dangerous     substrings.(CVE-2016-10739)

  - Use-after-free vulnerability in the clntudp_call     function in sunrpc/clnt_udp.c in the GNU C Library (aka     glibc or libc6) before 2.26 allows remote attackers to     have unspecified impact via vectors related to error     path.(CVE-2017-12133)

  - Stack-based buffer overflow in the glob implementation     in GNU C Library (aka glibc) before 2.24, when     GLOB_ALTDIRFUNC is used, allows context-dependent     attackers to cause a denial of service (crash) via a     long name.(CVE-2016-1234)

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.

  - 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)

An update of the glibc package has been released.

An update of [cracklib,libevent,libgcrypt,httpd,glibc] packages for PhotonOS has been released.

USN-3239-1 fixed vulnerabilities in the GNU C Library. Unfortunately, the fix for CVE-2016-3706 introduced a regression that in some circumstances prevented IPv6 addresses from resolving. This update reverts the change in Ubuntu 12.04 LTS. We apologize for the error.

It was discovered that the GNU C Library incorrectly handled the strxfrm() function. An attacker could use this issue to cause a denial of service or possibly execute arbitrary code. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2015-8982)

It was discovered that an integer overflow existed in the
_IO_wstr_overflow() function of the GNU C Library. An attacker could use this to cause a denial of service or possibly execute arbitrary code. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2015-8983)

It was discovered that the fnmatch() function in the GNU C Library did not properly handle certain malformed patterns.
An attacker could use this to cause a denial of service.
This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2015-8984)

Alexander Cherepanov discovered a stack-based buffer overflow in the glob implementation of the GNU C Library. An attacker could use this to specially craft a directory layout and cause a denial of service. (CVE-2016-1234)

Michael Petlan discovered an unbounded stack allocation in the getaddrinfo() function of the GNU C Library. An attacker could use this to cause a denial of service. (CVE-2016-3706)

Aldy Hernandez discovered an unbounded stack allocation in the sunrpc implementation in the GNU C Library. An attacker could use this to cause a denial of service. (CVE-2016-4429)

Tim Ruehsen discovered that the getaddrinfo() implementation in the GNU C Library did not properly track memory allocations. An attacker could use this to cause a denial of service. This issue only affected Ubuntu 16.04 LTS.
(CVE-2016-5417)

Andreas Schwab discovered that the GNU C Library on ARM 32-bit platforms did not properly set up execution contexts.
An attacker could use this to cause a denial of service.
(CVE-2016-6323).

USN-3239-1 fixed vulnerabilities in the GNU C Library. Unfortunately, the fix for CVE-2015-5180 introduced an internal ABI change within the resolver library. This update reverts the change. We apologize for the inconvenience.

Please note that long-running services that were restarted to compensate for the USN-3239-1 update may need to be restarted again.

Several vulnerabilities have been fixed in the Debian GNU C Library, eglibc :

CVE-2016-1234

Alexander Cherepanov discovered that the glibc's glob implementation suffered from a stack-based buffer overflow when it was called with the GLOB_ALTDIRFUNC flag and encountered a long file name.

CVE-2016-3075

The getnetbyname implementation in nss_dns was susceptible to a stack overflow and a crash if it was invoked on a very long name.

CVE-2016-3706

Michael Petlan reported that getaddrinfo copied large amounts of address data to the stack, possibly leading to a stack overflow. This complements the fix for CVE-2013-4458.

For Debian 7 'Wheezy', these problems have been fixed in version 2.13-38+deb7u11.

We recommend you to upgrade your eglibc packages.
