Gentoo Linux Security Advisory
Title: Cscope: Insecure creation of temporary files (GLSA 200412-11)
Severity: normal
Exploitable: local
Date: December 16, 2004
Bug(s): #71595
ID: 200412-11
Synopsis
Cscope is vulnerable to symlink attacks, potentially allowing a local user to overwrite arbitrary files.
Background
Cscope is a developer utility used to browse and manage source code.
Affected Packages
Package: dev-util/cscope
Vulnerable: < 15.5-r2
Unaffected: >= 15.5-r2
Architectures: All supported architectures
Description
Cscope creates temporary files in world-writable directories with predictable names.
Impact
A local attacker could create symbolic links in the temporary files directory, pointing to a valid file somewhere on the filesystem. When Cscope is executed, this would result in the file being overwritten with the rights of the user running the utility, which could be the root user.
Workaround
There is no known workaround at this time.
Resolution
All Cscope users should upgrade to the latest version: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=dev-util/cscope-15.5-r2" |
