CVE-2014-7940

Status Candidate

Overview

The collator implementation in i18n/ucol.cpp in International Components for Unicode (ICU) 52 through SVN revision 293126, as used in Google Chrome before 40.0.2214.91, does not initialize memory for a data structure, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted character sequence.

Mandriva Linux Security Advisory 2015-161 - The Regular Expressions package in International Components for Unicode 52 before SVN revision 292944 allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to a zero-length quantifier or look-behind expression. The collator implementation in i18n/ucol.cpp in International Components for Unicode 52 through SVN revision 293126 does not initialize memory for a data structure, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted character sequence. It was discovered that ICU incorrectly handled memory operations when processing fonts. If an application using ICU processed crafted data, an attacker could cause it to crash or potentially execute arbitrary code with the privileges of the user invoking the program.

Ubuntu Security Notice 2476-1 - Several memory corruption bugs were discovered in ICU. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service via renderer crash or execute arbitrary code with the privileges of the sandboxed render process. A use-after-free was discovered in the IndexedDB implementation. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via application crash or execute arbitrary code with the privileges of the user invoking the program. Various other issues were also addressed.
