TITLE

ICU Project ICU4C library contains multiple overflow vulnerabilities

DESCRIPTION

The resolveImplicitLevels function in common/ubidi.c in the Unicode Bidirectional Algorithm implementation in ICU4C in International Components for Unicode (ICU) before 55.1 does not properly track directionally isolated pieces of text, which allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly execute arbitrary code via crafted text. ICU Project ICU4C library, versions 52 through 54, contains a heap-based buffer overflow and an integer overflow. There is a security vulnerability in the 'resolveImplicitLevels' function in the common/ubidi.c file of the Unicode Bidirectional Algorithm implementation in the ICU4C version prior to ICU 55.1. The vulnerability stems from the fact that the program does not properly orientate and track isolated text fragments. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-3323-1 security@debian.org https://www.debian.org/security/ Laszlo Boszormenyi August 01, 2015 https://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : icu CVE ID : CVE-2014-6585 CVE-2014-8146 CVE-2014-8147 CVE-2015-4760 Debian Bug : 778511 784773 Several vulnerabilities were discovered in the International Components for Unicode (ICU) library. CVE-2015-4760 The Layout Engine was missing multiple boundary checks. These could lead to buffer overflows and memory corruption. Additionally, it was discovered that the patch applied to ICU in DSA-3187-1 for CVE-2014-6585 was incomplete, possibly leading to an invalid memory access. This could allow remote attackers to disclose portion of private memory via crafted font files. For the oldstable distribution (wheezy), these problems have been fixed in version 4.8.1.1-12+deb7u3. For the stable distribution (jessie), these problems have been fixed in version 52.1-8+deb8u2. For the testing distribution (stretch), these problems have been fixed in version 52.1-10. For the unstable distribution (sid), these problems have been fixed in version 52.1-10.

Hi, I have found two vulnerabilities in the ICU library while fuzzing LibreOffice, full details in the advisory below. Disclosure of these was done initially to LibreOffice and then to distro-security. I then reported it to Chromium, Android and finally CERT, so I ended up breaking the rules of distro-security which requires that any vulnerability reported to the list is made public in 14 days. I apologise for this to oss-security, distro-security and Solar Designer, and will not do it again. A full copy of the advisory below can be found in my repo at https://raw.githubusercontent.com/pedrib/PoC/master/generic/i-c-u-fail.txt. Regards, Pedro >> Heap overflow and integer overflow in ICU library >> Discovered by Pedro Ribeiro (pedrib@gmail.com), Agile Information Security ================================================================================= Disclosure: 04/05/2015 / Last updated: 04/05/2015 >> Background on the affected products: ICU is a mature, widely used set of C/C++ and Java libraries providing Unicode and Globalization support for software applications. ICU is widely portable and gives applications the same results on all platforms and between C/C++ and Java software. This library is used by LibreOffice and hundreds of other software packages. Proof of concept files can be downloaded from [1]. These files have been tested with LibreOffice 4.3.3.2 and LibreOffice 4.4.0-beta2 and ICU 52. Note that at this point in time it is unknown whether these vulnerabilities are exploitable. Thanks to CERT [2] for helping disclose these vulnerabilities. >> Technical details: #1 Vulnerability: Heap overflow CVE-2014-8146 The code to blame is the following (from ubidi.c:2148 in ICU 52): dirProp=dirProps[limit-1]; if((dirProp==LRI || dirProp==RLI) && limit<pBiDi->length) { pBiDi->isolateCount++; pBiDi->isolates[pBiDi->isolateCount].stateImp=stateImp; pBiDi->isolates[pBiDi->isolateCount].state=levState.state; pBiDi->isolates[pBiDi->isolateCount].start1=start1; } else processPropertySeq(pBiDi, &levState, eor, limit, limit); Under certain conditions, isolateCount is incremented too many times, which results in several out of bounds writes. See [1] for a more detailed analysis. #2 Vulnerability: Integer overflow CVE-2014-8147 The overflow is on the resolveImplicitLevels function (ubidi.c:2248): pBiDi->isolates[pBiDi->isolateCount].state=levState.state; pBiDi->isolates[].state is a int16, while levState.state is a int32. The overflow causes an error when performing a malloc on pBiDi->insertPoints->points because insertPoints is adjacent in memory to isolates[]. The Isolate struct is defined in ubidiimp.h:184 typedef struct Isolate { int32_t startON; int32_t start1; int16_t stateImp; int16_t state; } Isolate; LevState is defined in ubidi.c:1748 typedef struct { const ImpTab * pImpTab; /* level table pointer */ const ImpAct * pImpAct; /* action map array */ int32_t startON; /* start of ON sequence */ int32_t startL2EN; /* start of level 2 sequence */ int32_t lastStrongRTL; /* index of last found R or AL */ int32_t state; /* current state */ int32_t runStart; /* start position of the run */ UBiDiLevel runLevel; /* run level before implicit solving */ } LevState; >> Fix: The ICU versions that are confirmed to be affected are 52 to 54, but earlier versions might also be affected. Upgrade to ICU 55.1 to fix these vulnerabilities. Note that there are probably many other software packages that embed the ICU code and will probably also need to be updated. >> References: [1] https://github.com/pedrib/PoC/raw/master/generic/i-c-u-fail.7z [2] https://www.kb.cert.org/vuls/id/602540 .
