SynopsisThe remote Debian host is missing a security update.
DescriptionMultiple vulnerabilities have been discovered in libidn. The Common Vulnerabilities and Exposures project identifies the following problems :
When idn is reading one zero byte as input an out-of-bounds-read occurred.
An out-of-bounds stack read is exploitable in idna_to_ascii_4i.
stringprep_utf8_nfkc_normalize reject invalid UTF-8, causes a crash.
For Debian 7 'Wheezy', these problems have been fixed in version 1.25-2+deb7u2.
We recommend that you upgrade your libidn packages.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpgrade the affected packages.
