VAR-200311-0049

Vulnerability from variot - Updated: 2025-04-03 22:16

Mac OS X before 10.3 with core files enabled allows local users to overwrite arbitrary files and read core files via a symlink attack on core files that are created with predictable names in the /cores directory. Because of this, a local attacker may be able to overwrite arbitrary root owned files. Apple Mac OS X 10.3 (Panther) has been released to address multiple new and previously known vulnerabilities. These issues may cumulatively allow an attacker to cause denial of service, arbitrary code execution, privilege escalation and unauthorized access. The name of the core file is core.PID(*) , the owner of this file is ROOT, and the setting permission is 0400. Since /cores is globally writable by default, and the name of the core file is predictable, an attacker can establish a symbolic link to point to an important system file. When an application generates a CORE file, the system file will be overwritten, which may elevate privileges or cause denial of service. attack

    "data": "Mac OS X before 10.3 with core files enabled allows local users to overwrite arbitrary files and read core files via a symlink attack on core files that are created with predictable names in the /cores directory.  Because of this, a local attacker may be able to overwrite arbitrary root owned files. Apple Mac OS X 10.3 (Panther) has been released to address multiple new and previously known vulnerabilities. These issues may cumulatively allow an attacker to cause denial of service, arbitrary code execution, privilege escalation and unauthorized access. The name of the core file is core.PID(*) , the owner of this file is ROOT, and the setting permission is 0400. Since /cores is globally writable by default, and the name of the core file is predictable, an attacker can establish a symbolic link to point to an important system file. When an application generates a CORE file, the system file will be overwritten, which may elevate privileges or cause denial of service. attack",
