Description
This security bulletin contains information about 1 vulnerability.
1) Security restrictions bypass (CVE-ID: CVE-2013-2929)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: 5.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a local unauthenticated attacker to obtain potentially sensitive information and bypass security restrictions on the target system.
The weakness exists due to improper use of the get_dumpable function. A local attacker can gain access to potentially sensitive information from IA64 scratch registers via a crafted application, related to kernel/ptrace.c and arch/ia64/include/asm/processor.h, or bypass intended ptrace restrictions.
Remediation
