A vulnerability, which was classified as critical, has been found in Sun Solaris 8/9/10 (Operating System). This issue affects an unknown code of the component FreeType TTF Font Parser. The manipulation with an unknown input leads to a heap-based overflow vulnerability. Using CWE to declare the problem leads to CWE-122. A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). Impacted is availability. The summary by CVE is:

Integer signedness error in truetype/ttgload.c in Freetype 2.3.4 and earlier might allow remote attackers to execute arbitrary code via a crafted TTF image with a negative n_points value, which leads to an integer overflow and heap-based buffer overflow.
