Avoid out of boundary read on empty/broken file.
2017-04-02Check malloc return value for NULL.Tobias Stoeckmann-1/+1
If malloc cannot allocate enough memory, it could return NULL. This is not necessarily true for default Linux settings, but can be provoked there as well by adjusting proc entries. Other systems like the *BSD ones definitely do this. The function _emalloc exists for exactly this purpose, so use it instead of calling malloc directly.

2017-04-02Fixed memory leak on file name collision.Tobias Stoeckmann-0/+2
If feh_unique_filename encounters a file that already exists, the memory for the temporary filename is not released. As this happens in /tmp at some code places, an attacker could use this to spray the memory of feh, or simply triggering an out of memory condition.

2017-04-02Avoid out of boundary read on empty/broken file.Tobias Stoeckmann-2/+2
If ereadfile encounters an empty file or the file could not be read, an out ouf boundary read (and possible write) occurs. Always check the return value of fread to be > 0 before processing the result buffer. Signed-off-by: Tobias Stoeckmann <tobias@stoeckmann.org>
2017-04-02Always terminate strncpy results with '\0'.Tobias Stoeckmann-6/+12
The strncpy function does not guarantee to end the resulting character sequence with a terminating nul character if not enough space is available. This could be triggered by supplying a sufficiently long output_file option. Signed-off-by: Tobias Stoeckmann <tobias@stoeckmann.org>

Fix double-free/OOB-write while receiving IPC data
2017-03-23Fix double-free/OOB-write while receiving IPC dataTobias Stoeckmann-1/+1
If a malicious client pretends to be the E17 window manager, it is possible to trigger an out of boundary heap write while receiving an IPC message. The length of the already received message is stored in an unsigned short, which overflows after receiving 64 KB of data. It's comparably small amount of data and therefore achievable for an attacker. When len overflows, realloc() will either be called with a small value and therefore chars will be appended out of bounds, or len + 1 will be exactly 0, in which case realloc() behaves like free(). This could be abused for a later double-free attack as it's even possible to overwrite the free information -- but this depends on the malloc implementation.

2016-08-31Only use sysconf() if HOST_NAME_MAX is undefinedNiclas Zeising-2/+15
On some systsems sysconf() can return a very large value, unsuitable for use with malloc(). Only use sysconf() if HOST_NAME_MAX isn't avalable.
2016-08-31Fix build on FreeBSD.Niclas Zeising-6/+12
FreeBSD lacks the constant HOST_NAME_MAX, instead using sysconf(3) to find out the value of the maximum host name length at run time. Patch to use this instead of HOST_NAME_MAX. This brings with it the need to use malloc instead of using a statically sized buffer for the host name, since the size of the buffer cannot be known at run time. Errors from sysconf or malloc just means that the entire block of code is skipped over (the same way it's skipped if the call to gethostname() fails), rather than returning any kind of error to the caller or logging an error message somewhere.
