Ulf Harnhammar discovered multiple stack overflows in enscriptβs handling of special escape arguments. If a user or automated system were tricked into processing a malicious file with the β-eβ option enabled, a remote attacker could execute arbitrary code or cause enscript to crash, possibly leading to a denial of service.
