#vulnerability

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to win a race condition.

Heap-based buffer overflow in Windows Routing and Remote Access Service (RRAS) allows an authorized attacker to execute code over a network.

**According to the CVSS metric, the attack vector is local (AV:L). Why does the CVE title indicate that this is a remote code execution?** The word **Remote** in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. This means an attacker or victim needs to execute code from the local machine to exploit the vulnerability.

**What privileges could be gained by an attacker who successfully exploited the vulnerability?** An attacker who successfully exploited this vulnerability could gain specific limited SYSTEM privileges.

Deserialization of untrusted data in Microsoft Office SharePoint allows an authorized attacker to execute code over a network.

Untrusted pointer dereference in Microsoft Office Excel allows an unauthorized attacker to execute code locally.

Heap-based buffer overflow in Windows OLE allows an unauthorized attacker to execute code locally.

**What privileges could be gained by an attacker who successfully exploited this vulnerability?** An attacker who successfully exploited this vulnerability could gain SYSTEM privileges.

**According to the CVSS metrics, successful exploitation of this vulnerability could lead to a high loss of confidentiality (C:H), no effect on integrity (I:N) and some loss of availability (A:L). What does that mean for this vulnerability?** An attacker who successfully exploited this use after free vulnerability could view sensitive, previously freed memory heap information (Confidentiality) since the impacted component might be divulged to the attacker. While the attacker cannot make changes to disclosed information (Integrity), they might be able to force a crash within the function (Availability).

Improper link resolution before file access ('link following') in Host Process for Windows Tasks allows an authorized attacker to elevate privileges locally.
