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 est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.
Score EPSS
Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.
Percentile EPSS
Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres 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.
