CVE-2021-3999 (GCVE-0-2021-3999)
Vulnerability from cvelistv5 – Published: 2022-08-24 00:00 – Updated: 2025-12-02 20:54
VLAI
Summary
A flaw was found in glibc. An off-by-one buffer overflow and underflow in getcwd() may lead to memory corruption when the size of the buffer is exactly 1. A local attacker who can control the input buffer and size passed to getcwd() in a setuid program could use this flaw to potentially execute arbitrary code and escalate their privileges on the system.
Severity
7.8 (High)

CVE-2022-23400 (GCVE-0-2022-23400)
Vulnerability from cvelistv5 – Published: 2022-05-03 16:05 – Updated: 2025-04-15 19:04
VLAI
Summary
A stack-based buffer overflow vulnerability exists in the IGXMPXMLParser::parseDelimiter functionality of Accusoft ImageGear 19.10. A specially-crafted PSD file can overflow a stack buffer, which could either lead to denial of service or, depending on the application, to an information leak. An attacker can provide a malicious file to trigger this vulnerability.

Mitigation
Phase: Implementation
Description:
- When copying character arrays or using character manipulation methods, the correct size parameter must be used to account for the null terminator that needs to be added at the end of the array. Some examples of functions susceptible to this weakness in C include strcpy(), strncpy(), strcat(), strncat(), printf(), sprintf(), scanf() and sscanf().
