Summary

The PTR_MANGLE implementation in the GNU C Library (aka glibc or libc6) 2.4, 2.17, and earlier, and Embedded GLIBC (EGLIBC) does not initialize the random value for the pointer guard, which makes it easier for context-dependent attackers to control execution flow by leveraging a buffer-overflow vulnerability in an application and using the known zero value pointer guard to calculate a pointer address.

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.
  • Server Side Include (SSI) Injection
    An attacker can use Server Side Include (SSI) Injection to send code to a web application that then gets executed by the web server. Doing so enables the attacker to achieve similar results to Cross Site Scripting, viz., arbitrary code execution and information disclosure, albeit on a more limited scale, since the SSI directives are nowhere near as powerful as a full-fledged scripting language. Nonetheless, the attacker can conveniently gain access to sensitive files, such as password files, and execute shell commands.
  • Cross Zone Scripting
    An attacker is able to cause a victim to load content into their web-browser that bypasses security zone controls and gain access to increased privileges to execute scripting code or other web objects such as unsigned ActiveX controls or applets. This is a privilege elevation attack targeted at zone-based web-browser security. In a zone-based model, pages belong to one of a set of zones corresponding to the level of privilege assigned to that page. Pages in an untrusted zone would have a lesser level of access to the system and/or be restricted in the types of executable content it was allowed to invoke. In a cross-zone scripting attack, a page that should be assigned to a less privileged zone is granted the privileges of a more trusted zone. This can be accomplished by exploiting bugs in the browser, exploiting incorrect configuration in the zone controls, through a cross-site scripting attack that causes the attackers' content to be treated as coming from a more trusted page, or by leveraging some piece of system functionality that is accessible from both the trusted and less trusted zone. This attack differs from "Restful Privilege Escalation" in that the latter correlates to the inadequate securing of RESTful access methods (such as HTTP DELETE) on the server, while cross-zone scripting attacks the concept of security zones as implemented by a browser.
  • Cross Site Scripting through Log Files
    An attacker may leverage a system weakness where logs are susceptible to log injection to insert scripts into the system's logs. If these logs are later viewed by an administrator through a thin administrative interface and the log data is not properly HTML encoded before being written to the page, the attackers' scripts stored in the log will be executed in the administrative interface with potentially serious consequences. This attack pattern is really a combination of two other attack patterns: log injection and stored cross site scripting.
  • Command Line Execution through SQL Injection
    An attacker uses standard SQL injection methods to inject data into the command line for execution. This could be done directly through misuse of directives such as MSSQL_xp_cmdshell or indirectly through injection of data into the database that would be interpreted as shell commands. Sometime later, an unscrupulous backend application (or could be part of the functionality of the same application) fetches the injected data stored in the database and uses this data as command line arguments without performing proper validation. The malicious data escapes that data plane by spawning new commands to be executed on the host.

    descriptionUpdated glibc packages fixes the following security issues : Integer 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, which triggers a heap-based buffer overflow (CVE-2012-4412). 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). 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). NOTE! This is fixed by removing pt_chown wich may break chroots if their devpts was not mounted correctly (make sure to mount the devpts correctly with gid=5). sysdeps/posix/readdir_r.c in the GNU C Library (aka glibc or libc6) 2.18 and earlier allows context-dependent attackers to cause a denial of service (out-of-bounds write and crash) or possibly execute arbitrary code via a crafted (1) NTFS or (2) CIFS image (CVE-2013-4237). Multiple integer overflows in malloc/malloc.c in the GNU C Library (aka glibc or libc6) 2.18 and earlier allow context-dependent attackers to cause a denial of service (heap corruption) via a large value to the (1) pvalloc, (2) valloc, (3) posix_memalign, (4) memalign, or (5) aligned_alloc functions (CVE-2013-4332). A stack (frame) overflow flaw, which led to a denial of service (application crash), was found in the way glibc

  • NASL familyHuawei Local Security Checks
    NASL idEULEROS_SA-2019-1552.NASL
    descriptionAccording to the versions of the glibc packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : - It was discovered that the nss_files backend for the Name Service Switch in glibc would return incorrect data to applications or corrupt the heap (depending on adjacent heap contents). A local attacker could potentially use this flaw to execute arbitrary code on the system.(CVE-2015-5277) - A directory traveral flaw was found in the way glibc loaded locale files. An attacker able to make an application use a specially crafted locale name value (for example, specified in an LC_* environment variable) could possibly use this flaw to execute arbitrary code with the privileges of that application.(CVE-2014-0475) - It was found that out-of-range time values passed to the strftime() function could result in an out-of-bounds memory access. This could lead to application crash or, potentially, information disclosure.(CVE-2015-8776) - 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 PTR_MANGLE implementation in the GNU C Library (aka glibc or libc6) 2.4, 2.17, and earlier, and Embedded GLIBC (EGLIBC) does not initialize the random value for the pointer guard, which makes it easier for context-dependent attackers to control execution flow by leveraging a buffer-overflow vulnerability in an application and using the known zero value pointer guard to calculate a pointer address.(CVE-2013-4788) - An out-of-bounds read flaw was found in the way glibc

    NASL idNEWSTART_CGSL_NS-SA-2019-0012_GLIBC.NASL
    descriptionThe remote NewStart CGSL host, running version MAIN 5.04, has glibc packages installed that are affected by multiple vulnerabilities: - elf/dl-load.c in ld.so in the GNU C Library (aka glibc or libc6) through 2.11.2, and 2.12.x through 2.12.1, does not properly handle a value of $ORIGIN for the LD_AUDIT environment variable, which allows local users to gain privileges via a crafted dynamic shared object (DSO) located in an arbitrary directory. (CVE-2010-3847) - ld.so in the GNU C Library (aka glibc or libc6) before 2.11.3, and 2.12.x before 2.12.2, does not properly restrict use of the LD_AUDIT environment variable to reference dynamic shared objects (DSOs) as audit objects, which allows local users to gain privileges by leveraging an unsafe DSO located in a trusted library directory, as demonstrated by libpcprofile.so. (CVE-2010-3856) - Integer 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, which triggers a heap-based buffer overflow. (CVE-2012-4412) - 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) - 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) - It was found that getaddrinfo() did not limit the amount of stack memory used during name resolution. An attacker able to make an application resolve an attacker- controlled hostname or IP address could possibly cause the application to exhaust all stack memory and crash. (CVE-2013-1914, CVE-2013-4458) - 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.
