CVE-2008-3863
HighSummary
W funkcji read_special_escape w pliku src/psgen.c w GNU Enscript 1.6.1 i 1.6.4 beta występuje przepełnienie bufora na stosie, gdy włączona jest opcja -e (przetwarzanie specjalnych sekwencji). Umożliwia to zdalnym atakującym, przy pomocy spreparowanego pliku ASCII, wykonanie dowolnego kodu.
Risk Assessment
Podatność ta stwarza ryzyko wykonania złośliwego kodu na systemie ofiary, co może prowadzić do przejęcia kontroli nad systemem lub wycieku danych.
Recommendation
Zaleca się aktualizację do najnowszej wersji GNU Enscript, która eliminuje tę podatność, oraz ograniczenie dostępu do funkcji przetwarzania specjalnych sekwencji tylko do zaufanych użytkowników.

Original NVD description (English source)
Stack-based buffer overflow in the read_special_escape function in src/psgen.c in GNU Enscript 1.6.1 and 1.6.4 beta, when the -e (aka special escapes processing) option is enabled, allows user-assisted remote attackers to execute arbitrary code via a crafted ASCII file, related to the setfilename command.
