SilverCity: Insecure file permissions

1. Gentoo Linux Security Advisory

Package	Vulnerable versions	Unaffected versions	Architecture(s)
app-text/silvercity	< 0.9.5-r1	>= 0.9.5-r1	All supported architectures

Related bugreports: #93558

Executable files with insecure permissions can be modified causing an unsuspecting user to run arbitrary code.

2. Impact Information

SilverCity provides lexical analysis for over 20 programming and markup languages.

The SilverCity package installs three executable files with insecure permissions.

A local attacker could modify the executable files, causing arbitrary code to be executed with the permissions of an unsuspecting SilverCity user.

3. Resolution Information

There are no known workarounds at this time.

All SilverCity users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/silvercity-0.9.5-r1"
