Описание
The strftime function in the GNU C Library (aka glibc or libc6) before 2.23 allows context-dependent attackers to cause a denial of service (application crash) or possibly obtain sensitive information via an out-of-range time value.
It was found that out-of-range time values passed to the strftime() function could result in an out-of-bounds memory access. This could lead to application crash or, potentially, information disclosure.
Меры по смягчению последствий
Check time values before they are passed to strftime, or call strftime only with struct tm values computed by gmtime or localtime.
