PARTIAL Summary
An integer overflow in the implementation of the posix_memalign in memalign functions in the GNU C Library (aka glibc or libc6) 2.26 and earlier could cause these functions to return a pointer to a heap area that is too small, potentially leading to heap corruption.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Forced Integer Overflow This attack forces an integer variable to go out of range. The integer variable is often used as an offset such as size of memory allocation or similarly. The attacker would typically control the value of such variable and try to get it out of range. For instance the integer in question is incremented past the maximum possible value, it may wrap to become a very small, or negative number, therefore providing a very incorrect value which can lead to unexpected behavior. At worst the attacker can execute arbitrary code.

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.

This could lead to application crash or, potentially, arbitrary code execution.(CVE-2015-8778) - A stack-based buffer overflow was found in the way the libresolv library performed dual A/AAAA DNS queries. A remote attacker could create a specially crafted DNS response which could cause libresolv to crash or, potentially, execute code with the permissions of the user running the library. Note: this issue is only exposed when libresolv is called from the nss_dns NSS service module.(CVE-2015-7547) - A flaw was found in the regular expression matching routines that process multibyte character input. If an application utilized the glibc regular expression matching mechanism, an attacker could provide specially-crafted input that, when processed, would cause the application to crash.(CVE-2013-0242) - A flaw was found in the way memory was being allocated on the stack for user space binaries. If heap (or different memory region) and stack memory regions were adjacent to each other, an attacker could use this flaw to jump over the stack guard gap, cause controlled memory corruption on process stack or the adjacent memory region, and thus increase their privileges on the system. This is glibc-side mitigation which blocks processing of LD_LIBRARY_PATH for programs running in secure-execution mode and reduces the number of allocations performed by the processing of LD_AUDIT, LD_PRELOAD, and LD_HWCAP_MASK, making successful exploitation of this issue more difficult.(CVE-2017-1000366) - 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) - It was found that the files back end of Name Service Switch (NSS) did not isolate iteration over an entire database from key-based look-up API calls. An application performing look-ups on a database while iterating over it could enter an infinite loop, leading to a denial of service.(CVE-2014-8121) - Stack-based buffer overflow in the getaddrinfo function in sysdeps/posix/getaddrinfo.c in the GNU C Library (aka glibc or libc6) allows remote attackers to cause a denial of service (crash) via vectors involving hostent conversion. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-4458.(CVE-2016-3706) - In glibc 2.26 and earlier there is confusion in the usage of getcwd() by realpath() which can be used to write before the destination buffer leading to a buffer underflow and potential code execution.(CVE-2018-1000001) - Stack-based buffer overflow in string/strcoll_l.c in the GNU C Library (aka glibc or libc6) 2.17 and earlier allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long string that triggers a malloc failure and use of the alloca function.(CVE-2012-4424) - It was found that the dynamic loader did not sanitize the LD_POINTER_GUARD environment variable. An attacker could use this flaw to bypass the pointer guarding protection on set-user-ID or set-group-ID programs to execute arbitrary code with the permissions of the user running the application.(CVE-2015-8777) - The glob function in glob.c in the GNU C Library (aka glibc or libc6) before 2.27 contains a buffer overflow during unescaping of user names with the ~ operator.(CVE-2017-15804) - 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) - pt_chown in GNU C Library (aka glibc or libc6) before 2.18 does not properly check permissions for tty files, which allows local users to change the permission on the files and obtain access to arbitrary pseudo-terminals by leveraging a FUSE file system.(CVE-2013-2207) - A stack overflow flaw was found in glibc last seen 2020-03-17 modified 2019-05-14 plugin id 125004 published 2019-05-14 reporter This script is Copyright (C) 2019-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/125004 title EulerOS Virtualization 3.0.1.0 : glibc (EulerOS-SA-2019-1551) NASL family Huawei Local Security Checks NASL id EULEROS_SA-2019-1050.NASL description According to the version of the glibc packages installed, the EulerOS installation on the remote host is affected by the following vulnerability : - An integer overflow in the implementation of the posix_memalign in memalign functions in the GNU C Library (aka glibc or libc6) 2.26 and earlier could cause these functions to return a pointer to a heap area that is too small, potentially leading to heap corruption.(CVE-2018-6485) Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.
