| Vector | AV:N/AC:L/Au:N/C:N/I:N/A:P |
Name of the Vulnerable Software and Affected Versions
glibc versions prior to 2.16
Description
The issue allows context-dependent attackers to cause a denial of service, specifically an out-of-bounds read, when converting IBM930 encoded data to UTF-8 using the iconv function. This occurs when a multibyte character value of
0xffff is provided.Recommendations
For versions prior to 2.16, update to version 2.16 or later to resolve the issue. As a temporary workaround, consider restricting the input to the iconv function to prevent the use of the
0xffff multibyte character value.Exploit
