Description:
Two vulnerabilities have been reported in Cscope, which potentially can be exploited by malicious, local users to perform certain actions on a vulnerable system with escalated privileges and by malicious people to potentially compromise a user's system.
1) Temporary files are created insecurely, which can be exploited via symlink attacks to overwrite arbitrary files with the privileges of the user running Cscope.
2) A boundary error when parsing source code with "#include" statements can potentially be exploited to cause a buffer overflow when malicious source code is parsed.
Successful exploitation may potentially allow execution of arbitrary code.
The vulnerabilities have been reported in version 15.5. Other versions may also be affected.
Solution:
1) Grant only trusted users access to affected systems.
2) Don't open untrusted source code.

1) Jeremy Bae
