Summary

The GNU C Library (aka glibc or libc6) before 2.27 contains an off-by-one error leading to a heap-based buffer overflow in the glob function in glob.c, related to the processing of home directories using the ~ operator followed by a long string.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

    descriptionThis update addresses two security vulnerabilities : - CVE-2017-15670, CVE-2017-15671, CVE-2017-15804: Various vulnerabilities could lead to memory corruption in the `glob` and `glob64` function. (RHBZ#1505298, RHBZ##1504807) - CVE-2017-16997: Check for empty tokens before dynamic string token expansion in the dynamic linker, so that pre-existing privileged programs with `$ORIGIN` rpaths/runpaths do not cause the dynamic linker to search the current directory, potentially leading to privilege escalation. (RHBZ#1526866). - CVE-2018-1000001: `getcwd` would sometimes return a non-absolute path, confusing the `realpath` function, leading to privilege escalation in conjunction with user namespaces. (RHBZ#1533837) In addition, this update replaces the dynamic linker trampoline on x86-64 with a version which uses the `XSAVE` instruction if it is available. This improves compatibility with future hardware and compilers which do not follow the x86-64 ABI. This update also adjusts the thread stack size accounting to provide additional stack space compared to previous glibc versions (to avoid introducing RHBZ#1527887).

    NASL idFEDORA_2017-0D3FDD3D1F.NASL
    descriptionThis update adds support for the IBM858 codepage (RHBZ#1416405). It moves the `nss_compat` NSS service module to the main glibc package (RHBZ#1400538). As a security hardening measure, stdio streams are no longer flushed on process abort/assertion failure (RHBZ#1498880). `/var/db/Makefile` is now included in the `nss_db` package (RHBZ#1498900). Fixes installation related failures for IBM z Series (RHBZ#1499260). Two security fixes for the `glob` function are provided (CVE-2017-15670, CVE-2017-15671, RHBZ#1504807). An error in the `sysconf` function which caused it to return -1 for `_SC_IOV_MAX` has been corrected (RHBZ#1504165). The included upstream update from the glibc 2.26 stable branch improves C++ compatibility for ` <math.h>` functions and fixes a memory leak in malloc when thread local caches are in use. Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    descriptionstdlib/canonicalize.c in the GNU C Library (aka glibc or libc6) 2.27 and earlier, when processing very long pathname arguments to the realpath function, could encounter an integer overflow on 32-bit architectures, leading to a stack-based buffer overflow and, potentially, arbitrary code execution.(CVE-2018-11236) The GNU C Library (aka glibc or libc6) before 2.27 contains an off-by-one error leading to a heap-based buffer overflow in the glob function in glob.c, related to the processing of home directories using the ~ operator followed by a long string. (CVE-2017-15670) 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) An SSE2-optimized memmove implementation for i386 in sysdeps/i386/i686/multiarch/memcpy-sse2-unaligned.S in the GNU C Library (aka glibc or libc6) 2.21 through 2.27 does not correctly perform the overlapping memory check if the source memory range spans the middle of the address space, resulting in corrupt data being produced by the copy operation. This may disclose information to context-dependent attackers, or result in a denial of service, or, possibly, code execution.(CVE-2017-18269)

    descriptionIt was discovered that the GNU C library did not properly handle all of the possible return values from the kernel getcwd(2) syscall. A local attacker could potentially exploit this to execute arbitrary code in setuid programs and gain administrative privileges. (CVE-2018-1000001) A memory leak was discovered in the _dl_init_paths() function in the GNU C library dynamic loader. A local attacker could potentially exploit this with a specially crafted value in the LD_HWCAP_MASK environment variable, in combination with CVE-2017-1000409 and another vulnerability on a system with hardlink protections disabled, in order to gain administrative privileges. (CVE-2017-1000408) A heap-based buffer overflow was discovered in the _dl_init_paths() function in the GNU C library dynamic loader. A local attacker could potentially exploit this with a specially crafted value in the LD_LIBRARY_PATH environment variable, in combination with CVE-2017-1000408 and another vulnerability on a system with hardlink protections disabled, in order to gain administrative privileges. (CVE-2017-1000409) An off-by-one error leading to a heap-based buffer overflow was discovered in the GNU C library glob() implementation. An attacker could potentially exploit this to cause a denial of service or execute arbitrary code via a maliciously crafted pattern. (CVE-2017-15670) A heap-based buffer overflow was discovered during unescaping of user names with the ~ operator in the GNU C library glob() implementation. An attacker could potentially exploit this to cause a denial of service or execute arbitrary code via a maliciously crafted pattern. (CVE-2017-15804) It was discovered that the GNU C library dynamic loader mishandles RPATH and RUNPATH containing $ORIGIN for privileged (setuid or AT_SECURE) programs. A local attacker could potentially exploit this by providing a specially crafted library in the current working directory in order to gain administrative privileges. (CVE-2017-16997) It was discovered that the GNU C library malloc() implementation could return a memory block that is too small if an attempt is made to allocate an object whose size is close to SIZE_MAX, resulting in a heap-based overflow. An attacker could potentially exploit this to cause a denial of service or execute arbitrary code. This issue only affected Ubuntu 17.10. (CVE-2017-17426). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
