Description
This security bulletin contains information about 1 security vulnerability.
1) Cryptographic issues (CVE-ID: CVE-2012-3378)
The vulnerability allows a remote non-authenticated attacker to manipulate or delete data.
The register_application function in atk-adaptor/bridge.c in GNOME at-spi2-atk 2.5.2 does not seed the random number generator and generates predictable temporary file names, which makes it easier for local users to create or truncate files via a symlink attack on a temporary socket file in /tmp/at-spi2.
Remediation
Install update from vendor's website.
