A flaw in Haml allows arbitrary code execution as a result of improper filtering.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| dev-ruby/haml | * | < 5.1.2 | >= 5.1.2 |
Haml is a templating engine for HTML.
It was discovered that Haml was not correctly filtering out special characters which may be used for attributes.
A remote attacker could possibly execute arbitrary code with the privileges of the process or cause a Denial of Service condition.
There is no known workaround at this time.
All Haml users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-ruby/haml-5.1.2"
