Descriptions du CVE
Buffer overflow in McSubMgr ActiveX control (mcsubmgr.dll) in McAfee Security Center 6.0.23 for Internet Security Suite 2006, Wireless Home Network Security, Personal Firewall Plus, VirusScan, Privacy Service, SpamKiller, AntiSpyware, and QuickClean allows remote user-assisted attackers to execute arbitrary commands via long string parameters, which are later used in vsprintf.

| Nom de la faiblesse | 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 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.

'Name' => 'McAfee Subscription Manager Stack Buffer Overflow',
'Description' => %q{
This module exploits a flaw in the McAfee Subscription Manager ActiveX control.
Due to an unsafe use of vsprintf, it is possible to trigger a stack buffer overflow by
passing a large string to one of the COM-exposed routines, such as IsAppExpired.
This vulnerability was discovered by Karl Lynn of eEye.
