Summary

Heap-based buffer overflow in the zip_read_mac_metadata function in archive_read_support_format_zip.c in libarchive before 3.2.0 allows remote attackers to execute arbitrary code via crafted entry-size values in a ZIP archive.

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.

      - A flaw was found in the way libarchive handled hardlink
        archive entries of non-zero size. Combined with flaws in
        libarchive's file system sandboxing, this issue could
        cause an application using libarchive to overwrite
        arbitrary files with arbitrary data from the archive.
        (CVE-2016-5418)
    
      - Multiple out-of-bounds write flaws were found in
        libarchive. Specially crafted ZIP, 7ZIP, or RAR files
        could cause a heap overflow, potentially allowing code
        execution in the context of the application using
        libarchive. (CVE-2016-1541, CVE-2016-4300,
        CVE-2016-4302)
    
      - Multiple out-of-bounds read flaws were found in
        libarchive. Specially crafted LZA/LZH, AR, MTREE, ZIP,
        TAR, or RAR files could cause the application to read
        data out of bounds, potentially disclosing a small
        amount of application memory, or causing an application
        crash. (CVE-2015-8919, CVE-2015-8920, CVE-2015-8921,
        CVE-2015-8923, CVE-2015-8924, CVE-2015-8925,
        CVE-2015-8926, CVE-2015-8928, CVE-2015-8934)
    
      - Multiple NULL pointer dereference flaws were found in
        libarchive. Specially crafted RAR, CAB, or 7ZIP files
        could cause an application using libarchive to crash.
        (CVE-2015-8916, CVE-2015-8917, CVE-2015-8922)
    
      - Multiple infinite loop / resource exhaustion flaws were
        found in libarchive. Specially crafted GZIP or ISO files
        could cause the application to consume an excessive
        amount of resources, eventually leading to a crash on
        memory exhaustion. (CVE-2016-7166, CVE-2015-8930)
    
      - A denial of service vulnerability was found in
        libarchive. A specially crafted CPIO archive containing
        a symbolic link to a large target path could cause
        memory allocation to fail, causing an application using
        libarchive that attempted to view or extract such
        archive to crash. (CVE-2016-4809)
    
      - An integer overflow flaw, leading to a buffer overflow,
        was found in libarchive's construction of ISO9660
        volumes. Attempting to create an ISO9660 volume with 2
        GB or 4 GB file names could cause the application to
        attempt to allocate 20 GB of memory. If this were to
        succeed, it could lead to an out of bounds write on the
        heap and potential code execution. (CVE-2016-6250)
    
      - Multiple instances of undefined behavior due to
        arithmetic overflow were found in libarchive. Specially
        crafted MTREE archives, Compress streams, or ISO9660
        volumes could potentially cause the application to fail
        to read the archive, or to crash. (CVE-2015-8931,
        CVE-2015-8932, CVE-2016-5844)"

It is, therefore, affected by the following vulnerabilities : - An integer signedness error exists in libarchive in the archive_write_zip_data() function within file archive_write_set_format_zip.c due to improper conversion between unsigned and signed integer types when running on 64-bit CPUs. An unauthenticated, remote attacker can exploit this to cause a buffer overflow, resulting in a denial of service condition. (CVE-2013-0211) - A path traversal vulnerability exists in libarchive in the bsdcpio() function within file in cpio/cpio.c due to improper sanitization of user-supplied input. An unauthenticated, remote attacker can exploit this, via a specially crafted path in an archive, to write to arbitrary files. (CVE-2015-2304) - A heap-based buffer overflow condition exists in libarchive in the zip_read_mac_metadata() function within file archive_read_support_format_zip.c due to improper sanitization of user-supplied input. An unauthenticated, remote attacker can exploit this, via specially crafted entry-size values in a ZIP archive, to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-1541) - Multiple flaws exist in the OpenSSL library in the aesni_cbc_hmac_sha1_cipher() function in file crypto/evp/e_aes_cbc_hmac_sha1.c and the aesni_cbc_hmac_sha256_cipher() function in file crypto/evp/e_aes_cbc_hmac_sha256.c that are triggered when the connection uses an AES-CBC cipher and AES-NI is supported by the server. A man-in-the-middle attacker can exploit these to conduct a padding oracle attack, resulting in the ability to decrypt the network traffic.

description### SUMMARY An exploitable heap overflow vulnerability exists in the zip archive decompression functionality of libarchive. A specially crafted zip file can cause memory corruption leading to code execution. An attacker can send a malformed file to trigger this vulnerability. ### TESTED VERSIONS libarchive 3.1.2 ### PRODUCT URLS https://github.com/libarchive/libarchive ### CVSSv3 SCORE 7.8 - CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H ### DETAILS Vulnerable code exists in zip support format module: ``` libarchive\archive_read_support_format_zip.c: Line 2716 static int Line 2717 zip_read_mac_metadata(struct archive_read *a, struct archive_entry *entry, Line 2718 struct zip_entry *rsrc) Line 2719 { (...)

In line 2750 we see that based on "uncompressed_size" field of resource entry is used for allocation of the "metadata" buffer. This value is not checked, so a zero sized buffer may be allocated. Later on line 2787, the user controlled "compressed_size" field is copied into "mp" ("metadata") buffer. Depending on malloc implementation and heap state, malloc for size 0 will succeed and memory can be written outside the bounds of the undersized buffer. Attacker in this scenario can fully control amount and content of bytes used to overwrite. ### CRASH INFORMATION ``` Valgrind Analysis: ==59137== Memcheck, a memory error detector ==59137== Copyright (C) 2002-2013, and GNU GPL'd, by Julian Seward et al. ==59137== Using Valgrind-3.10.0.SVN and LibVEX; rerun with -h for copyright info ==59137== ==59137== Invalid write of size 2 ==59137== at 0x402EED3: memcpy (in /usr/lib/valgrind/vgpreload_memcheck-x86-linux.so) ==59137== by 0x8080AE1: zip_read_mac_metadata (archive_read_support_format_zip.c:2795) ==59137== by 0x8080F1F: archive_read_format_zip_seekable_read_header (archive_read_support_format_zip.c:2930) ==59137== by 0x804E3C6: _archive_read_next_header2 (archive_read.c:645) ==59137== by 0x804E47A: _archive_read_next_header (archive_read.c:683) ==59137== by 0x8088A13: archive_read_next_header (archive_virtual.c:148) ==59137== by 0x804A178: extract (ext.c:55) ==59137== by 0x804A271: main (ext.c:83) ==59137== Address 0x4459ae0 is 0 bytes after a block of size 0 alloc'd ==59137== at 0x402A17C: malloc (in /usr/lib/valgrind/vgpreload_memcheck-x86-linux.so) ==59137== by 0x808095C: zip_read_mac_metadata (archive_read_support_format_zip.c:2758) ==59137== by 0x8080F1F: archive_read_format_zip_seekable_read_header (archive_read_support_format_zip.c:2930) ==59137== by 0x804E3C6: _archive_read_next_header2 (archive_read.c:645) ==59137== by 0x804E47A: _archive_read_next_header (archive_read.c:683) ==59137== by 0x8088A13: archive_read_next_header (archive_virtual.c:148) ==59137== by 0x804A178: extract (ext.c:55) ==59137== by 0x804A271: main (ext.c:83) ==59137== ==59137== Invalid write of size 1 ==59137== at 0x402F04B: memcpy (in /usr/lib/valgrind/vgpreload_memcheck-x86-linux.so) ==59137== by 0x8080AE1: zip_read_mac_metadata (archive_read_support_format_zip.c:2795) ==59137== by 0x8080F1F: archive_read_format_zip_seekable_read_header (archive_read_support_format_zip.c:2930) ==59137== by 0x804E3C6: _archive_read_next_header2 (archive_read.c:645) ==59137== by 0x804E47A: _archive_read_next_header (archive_read.c:683) ==59137== by 0x8088A13: archive_read_next_header (archive_virtual.c:148) ==59137== by 0x804A178: extract (ext.c:55) ==59137== by 0x804A271: main (ext.c:83) ==59137== Address 0x4459b92 is not stack'd, malloc'd or (recently) free'd ``` ### TIMELINE * 2016-04-19 - Vendor Disclosure * 2016-05-01 - Public Release
