**Name of the Vulnerable Software and Affected Versions** Apache Portable Runtime versions 0.9.0 through 1.7.4 **Description** Lax permissions set by the Apache Portable Runtime library on Unix platforms would allow local users read access to named shared memory segments, potentially revealing sensitive application data. This issue does not affect non-Unix platforms, or builds with APR USE SHMEM SHMGET=1 (apr.h). **Recommendations** To resolve the issue, upgrade to APR version 1.7.5, which fixes this issue. As a temporary workaround, consider restricting access to the shared memory segments to minimize the risk of exploitation.

**Name of the Vulnerable Software and Affected Versions** chkrootkit versions prior to 0.50 **Description** The issue arises from the slapper function in chkrootkit, which fails to properly quote file paths. This allows local users to execute arbitrary code via a Trojan horse executable, but only when /tmp is not mounted with the noexec option. **Recommendations** For versions prior to 0.50, update to version 0.50 or later to resolve the issue. As a temporary workaround, consider mounting /tmp with the noexec option to minimize the risk of exploitation.
