Thunderbird segfaults on chinese characters
Last modified: 2007-11-30 17:10:59 EST
Description of problem: Thunderbird crashes when trying to read chinese emails containing chinese characters (for example in the sender) if the ttfonts-zh_CN package is installed. Version-Release number of selected component (if applicable): thunderbird-0.9-1.fc3 ttfonts-zh_CN-2.14-10 How reproducible: Always Steps to Reproduce: 1. Start Thunderbird 2. Open email with chinese sender and chinese chars 3. See Thunderbird crash Actual results: Segfault Expected results: Display of email Additional info: Here are some lines of straced to help track down the problem: [pid 4574] open("/usr/share/fonts/zh_CN/TrueType/zysong.ttf", O_RDONLY) = -1 ENOENT (No such file or directory) [pid 4574] open("/usr/share/fonts/zh_CN/TrueType/zysong.ttf", O_RDONLY) = -1 ENOENT (No such file or directory) [pid 4574] --- SIGSEGV (Segmentation fault) @ 0 (0) --- It seems that if the /usr/share/fonts/zh_CN directory exists thunderbird tries to opened the TrueType/zysong.ttf file from there. But this file is not part of the ttfonts-zh_CN package. The error is not handled correctly as it seems (probably thunderbird just reads without verifying the open result, didn't look into the src though).
Fedora Core 3 is now maintained by the Fedora Legacy project for security updates only. If this problem is a security issue, please reopen and reassign to the Fedora Legacy product. If it is not a security issue and hasn't been resolved in the current FC5 updates or in the FC6 test release, reopen and change the version to match. Thank you!
Confirmed that the problem was not found in FC6 test release with: fonts-chinese-3.02-7.fc6 thunderbird-1.5.0.7-3.fc6 and FC5 updates with fonts-chinese-3.02-4.1 thunderbird-1.5-6
