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.

Looking at https://github.com/adobe-flash/avmplus/blob/master/core/XMLListObject.cpp: bool XMLListObject::delUintProperty(uint32_t index) ... if (index >= _length()) [1] { return true; } ... px->childChanges(core->knodeRemoved, r->atom()); [2] ... m_children.removeAt(index); [3] In [1], the passed in index is validated. In [2], the callback can run actionscript, which might shrink the size of the current XMLList. In [3], the pre-validated index is used but it might now be invalid due to shrinking at [2]. Unfortunately, removeAt() does not behave well in the presence of an out-of-bounds index. The PoC works by triggering a wild copy in order to demonstrate the crash. But other side-effects are possible such as decrementing the refcount of an out-of-bounds index.
