Notifications for a CVE
Stay informed of any changes for a specific CVE.
CVE Descriptions
gcc 4.2.0 through 4.3.0 in GNU Compiler Collection, when casts are not used, considers the sum of a pointer and an int to be greater than or equal to the pointer, which might lead to removal of length testing code that was intended as a protection mechanism against integer overflow and buffer overflow attacks, and provide no diagnostic message about this removal. NOTE: the vendor has determined that this compiler behavior is correct according to section 6.5.6 of the C99 standard (aka ISO/IEC 9899:1999)

| 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.
