CVSS 3.0 Puntuación Base 8.8 (Impactos de la confidencialidad, la integridad y la disponibilidad). Vector CVSS: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H).

A buffer overflow in the _SanityCheck() function in the Common Desktop Environment version distributed with Oracle Solaris 10 1/13 (Update 11) and earlier allows local users to gain root privileges via a long calendar name or calendar owner passed to sdtcm_convert in a malicious calendar file. The open source version of CDE (based on the CDE 2.x codebase) is not affected, because it does not ship the vulnerable program. Versions 1.6 and below are affected.
