The vulnerability is caused due to a boundary error within the "read_special_escape()" function in src/psgen.c. This can be exploited to cause a stack-based buffer overflow by tricking the user into converting a malicious file. Successful exploitation allows execution of arbitrary code, but requires that special escapes processing is enabled with the "-e" option. The vulnerability is confirmed in versions 1.6.1 and 1.6.4 (beta). Other versions may also be affected. SOLUTION: Do not convert untrusted files. Various Linux vendors will issue patched versions soon. PROVIDED AND/OR DISCOVERED BY: Ulf Harnhammar, Secunia Research.
