Background
ytnef is a TNEF stream reader for reading winmail.dat files.
Description
The TNEFSubjectHandler function in lib/ytnef.c allows remote attackers to cause a denial-of-service (and potentially code execution) due to a double free which can be triggered via a crafted file. The SwapWord function in lib/ytnef.c allows remote attackers to cause a denial-of-service (and potentially code execution) due to a heap buffer overflow which can be triggered via a crafted file.
Impact
Please review the referenced CVE identifiers for details.
Workaround
There is no known workaround at this time.
Resolution
All ytnef users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-mail/ytnef-2.0"
