zxpdf in xpdf before 3.02-19 as packaged in Debian unstable and 3.02-12+squeeze1 as packaged in Debian squeeze deletes temporary files insecurely, which allows remote attackers to delete arbitrary files via a crafted .pdf.gz file name. zxpdf en xpdf, en versiones anteriores a la 3.02-19, tal y como se distribuye en Debian unstable y 3.02-12+squeeze1 tal y como se distribuye en Debian squeeze, elimina archivos temporales de forma no segura. Esto permite que los atacantes remotos eliminen archivos arbitrarios mediante un nombre de archivo .pdf.gz manipulado. • http://www.openwall.com/lists/oss-security/2014/02/08/5 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=635849 https://security-tracker.debian.org/tracker/CVE-2011-2902 • CWE-20: Improper Input Validation •
