Security Vulnerability in Simplified Chinese, Traditional Chinese, Korean, and Thai Language Input Methods

---

Security Vulnerability in Simplified Chinese, Traditional Chinese, Korean, and Thai Language Input Methods (see details below)

1. Impact

The Simplified Chinese, Traditional Chinese, Korean and Thai language input methods shipped with Solaris are impacted by a security vulnerability which may result in the creation of world writable or readable directories and files in a user's home directory. This may allow a local unprivileged user (or remote user if the affected files are shared remotely, for example via NFS) to read and modify directories and files in another user's home directory.

2. Contributing Factors

This issue can occur in the following releases:

SPARC Platform:

• Solaris 10 without patch 120412-08 AND patch 120414-20

X86 Platform:

• Solaris 10 without patch 120413-08 AND patch 120415-20

Notes:

1. Solaris 8 and Solaris 9 are not affected by this issue.
2. This issue only impacts systems with the Simplified Chinese, traditional Chinese, Korean, and Thai language locales installed.

The pkginfo(1) command can be used to check whether the following impacted packages are installed:

    Simplified Chinese: SUNWcleu2

    Traditional Chinese: SUNWhleu2

    Traditional Chinese (Hong Kong): SUNWhkleu

    Korean: SUNWkleu

    Thai: SUNWtleu

3. Symptoms

There are no predictable symptoms that would indicate the described issue has been exploited.

4. Workaround

To work around the described issue, change the access mode of the directories '.iiim/le' and '.Xlocale' to 0700 within the home directory of every user on the system; if such directories do not exist, create them (as "root" user) with 0700, as in the following example:

    # chmod -R 0700 .iiim/le .Xlocale
    # mkdir -pm 0700 .iiim/le .Xlocale

5. Resolution

This issue is addressed in the following releases:

SPARC platform:

• Solaris 10 with patch 120412-08 or later AND patch 120414-20 or later

X86 platform:

• Solaris 10 with patch 120413-08 or later AND patch 120415-20 or later

Note: After patches are installed, the system administrator will need to change the access mode of all existing directories and files under '.iiim/le/' and '.Xlocale' within the home directory for every local user.
