CVE-2007-4771

Status Candidate

Overview

Heap-based buffer overflow in the doInterval function in regexcmp.cpp in libicu in International Components for Unicode (ICU) 3.8.1 and earlier allows context-dependent attackers to cause a denial of service (memory consumption) and possibly have unspecified other impact via a regular expression that writes a large amount of data to the backtracking stack. NOTE: some of these details are obtained from third party information.

Ubuntu Security Notice 591-1
Posted Mar 24, 2008
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 591-1 - Will Drewry discovered that libicu did not properly handle '\0' when processing regular expressions. If an application linked against libicu processed a crafted regular expression, an attacker could execute arbitrary code with privileges of the user invoking the program. Will Drewry discovered that libicu did not properly limit its backtracking stack size. If an application linked against libicu processed a crafted regular expression, an attacker could cause a denial of service via resource exhaustion.

Gentoo Linux Security Advisory GLSA 200803-20 - Will Drewry (Google Security) reported a vulnerability in the regular expression engine when using back references to capture \0 characters (CVE-2007-4770). He also found that the backtracking stack size is not limited, possibly allowing for a heap-based buffer overflow (CVE-2007-4771). Versions less than 3.8.1-r1 are affected.

Debian Linux Security Advisory 1511-1
Posted Mar 3, 2008
Authored by Debian | Site debian.org

Debian Security Advisory 1511-1 - libicu in International Components for Unicode (ICU) 3.8.1 and earlier attempts to process backreferences to the nonexistent capture group zero (aka \0), which might allow context-dependent attackers to read from, or write to, out-of-bounds memory locations, related to corruption of REStackFrames. A heap-based buffer overflow in the doInterval function in regexcmp.cpp in libicu in International Components for Unicode (ICU) 3.8.1 and earlier allows context-dependent attackers to cause a denial of service (memory consumption) and possibly have unspecified other impact via a regular expression that writes a large amount of data to the backtracking stack.

Mandriva Linux Security Advisory 2008-026
Posted Jan 26, 2008
Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory - Will Drewry reported multiple flaws in how libicu processed certain malformed regular expressions. If an application linked against libicu, such as OpenOffice.org, processed a carefully-crafted regular expression, it could potentially cause the execution of arbitrary code with the privileges of the user running the application.
