Debian DLA-767-1 : curl security update
Medium Nessus Plugin ID 96183
SynopsisThe remote Debian host is missing a security update.
DescriptionIt was discovered that libcurl's implementation of the printf() functions triggers a buffer overflow when doing a large floating point output. The bug occurs when the conversion outputs more than 255 bytes.
The flaw happens because the floating point conversion is using system functions without the correct boundary checks.
If there are any application that accepts a format string from the outside without necessary input filtering, it could allow remote attacks.
This flaw does not exist in the command line tool.
For Debian 7 'Wheezy', these problems have been fixed in version 7.26.0-1+wheezy18.
We recommend that you upgrade your curl 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.
