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.

Notes: - Reliably reproduces with latest Adobe Flash Player Projector for Windows and Google Chrome for Windows. - The out-of-bounds read appears to be caused by an overly large index value (stored in the "EDX" register at the time of the crash) relative to a dynamically allocated buffer pointed to by "EAX". - The memory under "EAX" contains a section of the input file starting at offset 0x3453b7. - The index (EDX) value originates from offset 0x3453b8 in the file (at 1 byte offset relative to the EAX memory region). - Attached samples: signal_sigsegv_7ffff6d2184d_5692_9217909125eb9174614e1368d5f07173 (crashing file), 9217909125eb9174614e1368d5f07173 (original file). The total difference between the two files is 13 bytes. Proof of Concept: https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/37856.zip
