Description

Is this for Thunderbird only, or the libical package is also affected? I would verify that myself, but I do not have access to any related bug report mentioned here, neither to the upstream Mozilla bug. Mitigation: Thunderbird can be configured to use icaljs instead of libical by setting `calendar.icaljs = true` in preferences, mitigating this vulnerability. Created thunderbird tracking bugs for this issue: Affects: fedora-all [bug 1720423] In reply to comment #7: > Is this for Thunderbird only, or the libical package is also affected? This appears to be the original libical commit fixing the issue: * a4230eb8 - Fix a possible overrun in icalmemory_strdup_and_dequote if the last character is a backslash. Thanks for the patch Kent (2012-03-14 09:06:23 +1030) <Allen Winter> From git tags, this was included in the v1.0.0 release but not in v0.48.

I see. In that case libical in RHEL 6 is only affected by this one (there's 0.47 version, if I read it correctly). The RHEL 7 and 8 are at libical 3.0.x.
