SB2011033101 - Multiple vulnerabilities in logrotate

Description

This security bulletin contains information about 3 vulnerabilities.

1) Race condition (CVE-ID: CVE-2011-1098)

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

Race condition in the createOutputFile function in logrotate.c in logrotate 3.7.9 and earlier allows local users to read log data by opening a file before the intended permissions are in place.

2) Input validation error (CVE-ID: CVE-2011-1154)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

The shred_file function in logrotate.c in logrotate 3.7.9 and earlier might allow context-dependent attackers to execute arbitrary commands via shell metacharacters in a log filename, as demonstrated by a filename that is automatically constructed on the basis of a hostname or virtual machine name.

3) Resource management error (CVE-ID: CVE-2011-1155)

CWE-ID: CWE-399 - Resource Management Errors

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

The writeState function in logrotate.c in logrotate 3.7.9 and earlier might allow context-dependent attackers to cause a denial of service (rotation outage) via a (1) (newline) or (2) (backslash) character in a log filename, as demonstrated by a filename that is automatically constructed on the basis of a hostname or virtual machine name.
