Descriptions du CVE
Heap-based buffer overflow in the pefromupx function in libclamav/upx.c in Clam AntiVirus (ClamAV) 0.81 through 0.88.3 allows remote attackers to execute arbitrary code via a crafted UPX packed file containing sections with large rsize values.

| 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.

ClamAV is prone to a heap buffer-overflow vulnerability because it fails to properly bounds-check user-supplied data before copying it to an insufficiently sized memory buffer.
This issue occurs when the application attempts to handle compressed UPX files.
Exploiting this issue could allow attacker-supplied machine code to execute in the context of the affected application. The issue would occur when the malformed file is scanned manually or automatically in deployments such as email gateways.
ClamAV versions 0.88.2 and 0.88.3 are vulnerable to this issue; prior versions may also be affected.
