An update that fixes three vulnerabilities is now available.

 

Description:

 

 

LibXFont was updated to fix security problems that could be used by local

attackers to gain X server privileges (root).

 

The following security issues have been fixed:

 

*

 

CVE-2015-1802: The bdf parser reads a count for the number of

properties defined in a font from the font file, and allocates arrays with

entries for each property based on that count. It never checked to see if

that count was negative, or large enough to overflow when multiplied by

the size of the structures being allocated, and could thus allocate the

wrong buffer size, leading to out of bounds writes.

 

*

 

CVE-2015-1803: If the bdf parser failed to parse the data for the

bitmap for any character, it would proceed with an invalid pointer to the

bitmap data and later crash when trying to read the bitmap from that

pointer.

 

*

 

CVE-2015-1804: The bdf parser read metrics values as 32-bit

integers, but stored them into 16-bit integers. Overflows could occur in

various operations leading to out-of-bounds memory access.

 

Security Issues:

 

* CVE-2015-1802

 

* CVE-2015-1803

 

* CVE-2015-1804
