TITLE

procps-ng Integer overflow vulnerability

DESCRIPTION

procps-ng before version 3.3.15 is vulnerable to multiple integer overflows leading to a heap corruption in file2strvec function. This allows a privilege escalation for a local attacker who can create entries in procfs by starting processes, which could result in crashes or arbitrary code execution in proc utilities run by other users. procps-ng Contains an integer overflow vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Procps-ng Procps is prone to the following security vulnerabilities: 1. A local security-bypass vulnerability 2. A local privilege-escalation vulnerability 3. A local denial-of-service vulnerability 4. Multiple local integer-overflow vulnerabilities 5. A stack-based buffer-overflow vulnerability Attackers can exploit these issues to execute arbitrary code in the context of the user running the affected application or perform unauthorized actions. Failed exploit attempts will likely cause a denial-of-service condition. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 201805-14 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: Normal Title: procps: Multiple vulnerabilities Date: May 30, 2018 Bugs: #656022 ID: 201805-14 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======== Multiple vulnerabilities have been found in procps, the worst of which could result in the execution of arbitrary code.
