1. Gentoo Linux Security Advisory

Package	Vulnerable versions	Unaffected versions	Architecture(s)
net-analyzer/honeyd	< 1.5c-r1	>= 1.5c-r1	All supported architectures

Related bugreports: #237481

An insecure temporary file usage has been reported in Honeyd, possibly leading to symlink attacks.

2. Impact Information

Honeyd is a small daemon that creates virtual hosts on a network.

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

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

3. Resolution Information

There is no known workaround at this time.

All Honeyd users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-analyzer/honeyd-1.5c-r1"
