CVE Descriptions

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.

CVE Informations

Related Weaknesses

CWE-ID Weakness Name 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. 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 is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

EDB Verified : Yes

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
