Description
This security bulletin contains information about 2 vulnerabilities.
1) Input validation error (CVE-ID: CVE-2015-1805)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
The (1) pipe_read and (2) pipe_write implementations in fs/pipe.c in the Linux kernel before 3.16 do not properly consider the side effects of failed __copy_to_user_inatomic and __copy_from_user_inatomic calls, which allows local users to cause a denial of service (system crash) or possibly gain privileges via a crafted application, aka an "I/O vector array overrun."
2) Improper input validation (CVE-ID: CVE-2015-4700)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper input validation error within the bpf_int_jit_compile() function in arch/x86/net/bpf_jit_comp.c. A local user can perform a denial of service (DoS) attack.
