t1utils: Arbitrary code execution

Background

t1utils is a collection of simple Type 1 font manipulation programs.

Description

t1utils has a buffer overflow in the set_cs_start function in t1disasm.c.

Impact

A remote attacker could cause a denial of service and possibly execute arbitrary code via a crafted font file.

Workaround

There is no known workaround at this time.

Resolution

All t1utils users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=app-text/t1utils-1.39"
