CVE Informations
Related Weaknesses
| Weakness Name | Source | |
|---|---|---|
| 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.

It has been reported that the HPUX wall executable may be prone to a buffer overflow condition. This buffer overflow is alleged to be triggered when an excessive amount of data is redirected into wall as a message intended to be broadcast.
It may be possible for remote attackers to corrupt sensitive regions of memory with attacker-supplied values, possibly resulting in execution of arbitrary code.
perl -e 'print "A" x 9000' > /tmp/out
