Public bug reported:
After unattended-upgrades on Ubuntu 20.04 with Ubuntu Pro (esm-apps enabled),
Roundcube started returning HTTP 500 when opening some messages.
PHP error:
PHP Parse error: syntax error, unexpected 'private' (T_PRIVATE)
in /usr/share/roundcube/program/lib/Roundcube/rcube_washtml.php on line 527
Inspection shows a syntax error earlier in the file:
/usr/share/roundcube/program/lib/Roundcube/rcube_washtml.php:509
if ($attr_value === $val) {{
The double '{' causes unbalanced braces and triggers the parse error.
Fix:
Changing it to a single '{' resolves the issue immediately:
if ($attr_value === $val) {
Environment:
- Ubuntu 20.04 (focal)
- roundcube-core 1.4.3+dfsg.1-1ubuntu0.1~esm6
- Installed from: https://esm.ubuntu.com/apps/ubuntu focal-apps-security
Notes:
- dpkg -V did not report this file as modified
- Issue only affects messages that trigger HTML sanitization path
