CVE Descriptions

Multiple buffer overflows in the (1) read and (2) write handlers in the Omnikey CardMan 4040 driver in the Linux kernel before 2.6.21-rc3 allow local users to gain privileges.

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.

// source: https://www.securityfocus.com/bid/23355/info The 'man' command is prone to a local buffer-overflow vulnerability because it fails to properly bounds-check user-supplied input before using it in a memory copy operation. NOTE: Presumably, this issue is exploitable only when 'man' has been installed setuid. Exploiting this issue allows attackers to execute malicious machine code with the privileges of the 'man' utility. This can result in the compromise of affected computers. Failed exploit attempts will likely result in denial-of-service conditions.

The information presented on CVE Find originates from several carefully selected reference sources. CVE data is provided by MITRE Corporation and the National Vulnerability Database (NVD). The Known Exploited Vulnerabilities (KEV) catalog is sourced from the Cybersecurity and Infrastructure Security Agency (CISA), while EPSS scores come from FIRST.org. Additionally, data regarding software weaknesses (CWE) and common attack patterns (CAPEC) is maintained by MITRE Corporation, and information on hardware and software configurations (CPE) is provided by the NVD.
