Categoría:	Mageia Linux Local Security Checks
Título:	Mageia: Security Advisory (MGASA-2014-0496)
Resumen:	The remote host is missing an update for the 'glibc' package(s) announced via the MGASA-2014-0496 advisory.
Descripción:	Summary: The remote host is missing an update for the 'glibc' package(s) announced via the MGASA-2014-0496 advisory. Vulnerability Insight: The function wordexp() fails to properly handle the WRDE_NOCMD flag when processing arithmetic inputs in the form of '$((... ``))' where '...' can be anything valid. The backticks in the arithmetic epxression are evaluated by in a shell even if WRDE_NOCMD forbade command substitution. This allows an attacker to attempt to pass dangerous commands via constructs of the above form, and bypass the WRDE_NOCMD flag. This update fixes the issue (CVE-2014-7817). Affected Software/OS: 'glibc' package(s) on Mageia 3, Mageia 4. Solution: Please install the updated package(s). CVSS Score: 4.6 CVSS Vector: AV:L/AC:L/Au:N/C:P/I:P/A:P
