Description:
Some vulnerabilities have been reported in NetBSD, which can be exploited by malicious, local users to gain escalated privileges, or by malicious users to cause a DoS (Denial of Service) and compromise a vulnerable system, or by malicious people to bypass certain security restrictions and compromise a user's system.
1) Some boundary errors exist in the telnet client. This can be exploited by malicious people to compromise a user's system.
For more information:
SA14745
2) Multiple vulnerabilities exist in CVS. These can be exploited by malicious users to cause a DoS (Denial of Service) and compromise a vulnerable system, or by malicious, local users to perform certain actions on a vulnerable system with escalated privileges.
For more information:
SA11641
SA11817
SA16553
SA14976
3) An integer overflow error in the FreeBSD compatibility code can lead to heap corruption. This may be exploited by local users to cause a DoS and potentially to execute arbitrary code with root privileges.
4) Temporary files are being created insecurely in the "/tmp" directory by "imake" when generating pre-formatted manual pages. This can be exploited via symlink attacks to create or overwrite arbitrary files with the privileges of the user running the affected script.
5) A vulnerability exists in OpenSSL, which potentially can be exploited by malicious people to bypass certain security restrictions.
For more information:
SA17151
6) A security issue exists in ntpd, which can cause ntpd to run with incorrect group permissions.
For more information:
SA16602
7) An error exists the "ptrace()" function when checking for process privileges before attaching to a process. This can be exploited to attach to a suid process that calls "exec()". This potentially allows local privilege escalation by altering the behaviour of the process or by injecting additional syscalls.
