Stack-based buffer overflow in VideoLAN VLC media player before 2.0.1 allows remote attackers to execute arbitrary code via a crafted MMS:// stream.

CVE Informations

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. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.

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.

The vulnerability is due to a dangerous use of sprintf which can result in a stack buffer overflow when handling a malicious MMS URI. This module uses the browser as attack vector. A specially crafted MMS URI is used to trigger the overflow and get flow control through SEH overwrite. Control is transferred to code located in the heap through a standard heap spray.
