Summary

Integer overflow in the read_SubStreamsInfo function in archive_read_support_format_7zip.c in libarchive before 3.2.1 allows remote attackers to execute arbitrary code via a 7zip file with a large number of substreams, which triggers a heap-based buffer overflow.

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.

    "Security Fix(es) :
    
      - 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)"

description### SUMMARY An exploitable \heap overflow vulnerability exists in the 7zip read_SubStreamsInfo functionality of libarchive. A specially crafted 7zip file can cause a integer overflow resulting in memory corruption that can lead 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 7zip support format module: libarchive\archivereadsupportformat7zip.c: ``` (...) #define UMAX_ENTRY ARCHIVE_LITERAL_ULL(100000000) (...) Line 2129 static int Line 2130 read_SubStreamsInfo(struct archive_read *a, struct _7z_substream_info *ss, Line 2131 struct _7z_folder *f, size_t numFolders) Line 2132 { Line 2133 const unsigned char *p; Line 2134 uint64_t *usizes; Line 2135 size_t unpack_streams; Line 2136 int type; Line 2137 unsigned i; Line 2138 uint32_t numDigests; (...)

This variable is sizet what means that on x86 platform will be 32bit unsigned int. Maxium value of of "numUnpackStreams" is equal to UMAXENTRY. To overflow "unpackstreams" variable we need to have 7zip file with number of folders "numFolders" bigger than 42 and "numUnpackStreams" with sufficient values. The overflowed value is also used as size parameter in calloc in lines 2166-2171. Interesting buffer allocated there for us is "ss->unpackSizes". Later in lines 2187-2194 based on "numFolders" and "numUnpackStreams" of each folder, a 64bit unsigned integer (maximum) is read from the file and stored into buffer "usizes" which is indeed "ss->unpackSizes" ( line 2177 ) causing a heap based buffer overflow after some iterations. At this point the attacker controls the length and contents of the memory corruption. ### CRASH INFORMATION ``` valgrind output: ==33167== Memcheck, a memory error detector ==33167== Copyright (C)
