| Package | Type | Release | Fixed Version | Urgency | Origin | Debian Bugs |
|---|---|---|---|---|---|---|
| tigervnc | source | (unstable) | (not affected) | |||
| vnc4 | source | (unstable) | 4.1.1+X4.3.0+t-1 | unimportant |
- tigervnc <not-affected> (Fixed before initial release in Debian)
may affect related *VNC implementations if built with NDEBUG
e.g. vnc4 seems to have similar code in common/rfb/zrleDecode.h
starting with 4.1.1+X4.3.0+t-1 it's a transitional package
