1. Gentoo Linux Security Advisory

Package	Vulnerable versions	Unaffected versions	Architecture(s)
sci-electronics/geda	< 1.4.0-r1	>= 1.4.0-r1	All supported architectures

Related bugreports: #247538

An insecure temporary file usage has been reported in gEDA, allowing for symlink attacks.

2. Impact Information

gEDA is an Electronic Design Automation tool used for electrical circuit design.

Dmitry E. Oboukhov reported an insecure temporary file usage within the sch2eaglepos.sh script.

A local attacker could perform symlink attacks to overwrite arbitrary files with the privileges of the user running the application.

3. Resolution Information

There is no known workaround at this time.

All gEDA users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
