Some vulnerabilities have been reported in CUPS, which potentially can be exploited by malicious people to compromise a vulnerable system.
1) Two boundary errors exist in the implementation of the HP-GL/2 filter. These can be exploited to cause buffer overflows via HP-GL/2 files containing overly large pen numbers.
2) A boundary error exists within the "read_rle16()" function when processing SGI (Silicon Graphics Image) files. This can be exploited to cause a heap-based buffer overflow via a specially crafted SGI file.
3) An integer overflow error exists within the "WriteProlog()" function included in the "texttops" utility. This can be exploited to cause a heap-based buffer overflow via a specially crafted file.
Successful exploitation of the vulnerabilities may allow execution of arbitrary code.
The vulnerabilities are reported in versions prior to 1.3.9.
Solution: Update to version 1.3.9.
