Description Martin Prpič 2015-02-24 14:10:37 UTC 
An integer overflow flaw, leading to a heap-based buffer overflow, was found in glibc's _IO_wstr_overflow() function. If an application used this function, it could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application.
