Vulnerabilities > CVE-2015-1472 - Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products
Attack vector
UNKNOWN Attack complexity
UNKNOWN Privileges required
UNKNOWN Confidentiality impact
UNKNOWN Integrity impact
UNKNOWN Availability impact
UNKNOWN Summary
The ADDW macro in stdio-common/vfscanf.c in the GNU C Library (aka glibc or libc6) before 2.21 does not properly consider data-type size during memory allocation, which allows context-dependent attackers to cause a denial of service (buffer overflow) or possibly have unspecified other impact via a long line containing wide characters that are improperly handled in a wscanf call.
Vulnerable Configurations
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.

Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The glibc packages provide the standard C libraries (libc), POSIX thread libraries (libpthread), standard math libraries (libm), and the Name Server Caching Daemon (nscd) used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly. 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).

Together with typical OpenSSH configurations (with suitable AcceptEnv settings in sshd_config), this could conceivably be used to bypass ForceCommand restrictions (or restricted shells), assuming the attacker has sufficient level of access to a file system location on the host to create crafted locale definitions there (CVE-2014-0475). David Reid, Glyph Lefkowitz, and Alex Gaynor discovered a bug where posix_spawn_file_actions_addopen fails to copy the path argument (glibc bz #17048) which can, in conjunction with many common memory management techniques from an application, lead to a use after free, or other vulnerabilities (CVE-2014-4043). This update also fixes the following issues: x86: Disable x87 inline functions for SSE2 math (glibc bz #16510) malloc: Fix race in free() of fastbin chunk (glibc bz #15073) Tavis Ormandy discovered a heap-based buffer overflow in the transliteration module loading code. As a result, an attacker who can supply a crafted destination character set argument to iconv-related character conversation functions could achieve arbitrary code execution. This update removes support of loadable gconv transliteration modules. Besides the security vulnerability, the module loading code had functionality defects which prevented it from working for the intended purpose (CVE-2014-5119). Adhemerval Zanella Netto discovered out-of-bounds reads in additional code page decoding functions (IBM933, IBM935, IBM937, IBM939, IBM1364) that can be used to crash the systems, causing a denial of service conditions (CVE-2014-6040).

The strftime() function access invalid memory when passed out-of-range data, resulting in a crash (CVE-2015-8776). An integer overflow was found in the __hcreate_r() function (CVE-2015-8778). Multiple unbounded stack allocations were found in the catopen() function (CVE-2015-8779). Please review the CVEs referenced below for additional vulnerabilities that had already been fixed in previous versions of sys-libs/glibc, for which we have not issued a GLSA before. Impact : A remote attacker could exploit any application which performs host name resolution using getaddrinfo() in order to execute arbitrary code or crash the application. The other vulnerabilities can possibly be exploited to cause a Denial of Service or leak information. Workaround : A number of mitigating factors for CVE-2015-7547 have been identified.
