| Author | Note |
|---|---|
| leosilva | According with debian versions bellow 52.1.8 are not affected because code is not present, though, it needs further confirmation. keep precise/trusty as needs-triage. |
| mdeslaur | in xenial and older releases, vulnerable code looks to be in UnicodeString::doReplace, need to investigate |
| leosilva | doAppend was write based on doReplace, that originally shipped the vul code more info, check commit 3d77fc18b8b. Marking precise/trusty as needed. |
