Date Reported:

19 Apr 2017

Affected Packages:

icu

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 860314.
In Mitre's CVE dictionary: CVE-2017-7867, CVE-2017-7868.

More information:

It was discovered that icu, the International Components for Unicode library, did not correctly validate its input. An attacker could use this problem to trigger an out-of-bound write through a heap-based buffer overflow, thus causing a denial of service via application crash, or potential execution of arbitrary code.

For the stable distribution (jessie), these problems have been fixed in version 52.1-8+deb8u5.

For the upcoming stable (stretch) and unstable (sid) distributions, these problems have been fixed in version 57.1-6.

We recommend that you upgrade your icu packages.
