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.

Running the attached swf file in Google Chrome (Linux x64) will eventually result in dialog offering to terminate the slow script. (Not the Google Chrome infobar that says that Flash isn't responding, but the dialog that appears after that.)
Upon electing to terminate the script, a crash occurs.
It is not known whether this bug can be triggered or not without user interaction.
The crashing swf is signal_sigsegv_7ffff5ce5ea4_6963_b1d6342468487426c7ea26c725453e7d.swf
The base file from which the mutated file was generated is b1d6342468487426c7ea26c725453e7d.swf
On Linux x64, the crash looks like this:
=> 0x00007f6931525318: andl $0xffffffbf,0x3c(%rax)
rax 0x7ff8000000000000 9221120237041090560
And if we look back in the assembly a bit, the wild value has come from %rbx that points to a block of wild values.
