Descriptions du CVE

Heap-based buffer overflow in libmpdemux/aviheader.c in MPlayer 1.0rc1 and earlier allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a .avi file with certain large "indx truck size" and nEntriesInuse values, and a certain wLongsPerEntry value.

CWE-ID Nom de la faiblesse Source
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.

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.

source: https://www.securityfocus.com/bid/25648/info MPlayer is prone to a heap-based buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied input data. Attackers can exploit this issue to execute arbitrary code with the privileges of the user running the application. Failed attacks will result in denial-of-service conditions. MPlayer 1.0rc1 is vulnerable; other versions may also be affected. NOTE: The vendor states that this issue is present only on operating systems with a 'calloc' implementation that is prone to an integer-overflow issue. The following proof-of-concept AVI header data is available: 69 6E 64 78 00 FF FF FF 01 11 64 73 20 00 00 10 indx truck size 0xffffff00 wLongsPerEntry 0x0001 BIndexSubType is 0x64 bIndexType is 0x73 nEntriesInuse is 0x10000020
