Description

This security bulletin contains information about 2 vulnerabilities.


1) Input validation error (CVE-ID: CVE-2012-5667)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P/U:Green


The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

Multiple integer overflows in GNU Grep before 2.11 might allow context-dependent attackers to execute arbitrary code via vectors involving a long input line that triggers a heap-based buffer overflow.


2) Out-of-bounds read (CVE-ID: CVE-2015-1345)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary error in the bmexec_trans function in kwset.c. A remote attacker can create crafted input when using the -F option, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
