Synopsis

The remote Debian host is missing a security-related update.

Description

Several vulnerabilities were discovered in the International Components for Unicode (ICU) library.

- CVE-2014-9911 Michele Spagnuolo discovered a buffer overflow vulnerability which might allow remote attackers to cause a denial of service or possibly execute arbitrary code via crafted text.

- CVE-2015-2632 An integer overflow vulnerability might lead into a denial of service or disclosure of portion of application memory if an attacker has control on the input file.

- CVE-2015-4844 Buffer overflow vulnerabilities might allow an attacker with control on the font file to perform a denial of service or, possibly, execute arbitrary code.

- CVE-2016-0494 Integer signedness issues were introduced as part of the CVE-2015-4844 fix.

- CVE-2016-6293 A buffer overflow might allow an attacker to perform a denial of service or disclosure of portion of application memory.

- CVE-2016-7415 A stack-based buffer overflow might allow an attacker with control on the locale string to perform a denial of service and, possibly, execute arbitrary code.

Solution

Upgrade the icu packages.

For the stable distribution (jessie), these problems have been fixed in version 52.1-8+deb8u4.
