Description:
Some vulnerabilities have been discovered in GNU Enscript, which can be exploited by malicious people to compromise a vulnerable system.
1) A vulnerability is caused due to a boundary error within the "read_special_escape()" function in src/psgen.c when processing the "setfilename" escape sequence. This can be exploited to cause a stack-based buffer overflow by tricking the user into converting a malicious file.
2) A vulnerability is caused due to a boundary error within the "read_special_escape()" function in src/psgen.c when processing the "font" escape sequence. 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 vulnerabilities are confirmed in versions 1.6.1 and 1.6.4 (beta). Other versions may also be affected.
