In fact, top was made locale independent back +in release 3.3.13 (April, 2018). However, that bug did +reveal some misplaced logic which this patch corrects. + +Prompted by the Qualys audit, all rcfile field strings +were checked for potential duplicates which could only +have resulted from some user's manual/malicious edits. + +Unfortunately, that code was executed before top had a +chance to enforce the proper/maximum string length (in +the event an extremely old rcfile had just been read). +This created some potential string overrun references. + +In top's original 3.3.15 implementation, the potential +overrun extended for 15 characters. That is the number +of field characters added with 3.3.9 (December, 2013). +But, since strchr() was used, no error exit was taken. + +In the revised 3.3.16 implementation, the strchr() was +replaced with '&w->rc.fieldscur[n]'. This held overrun +to a single position while producing an error message. + +So, this commit just moves that logic to a point where +fieldscur is guaranteed to be longer than EU_MAXPFLGS. + +Reference(s): +https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=951335 +. revised 3.3.16 validation logic +commit 291d98ee5036567f93d21bc11142b0a7e2ee70ae +. original 3.3.15 validation logic +commit fdb58974e24c025a1f866f324c62f1d8f96234f8 + +Signed-off-by: Jim Warner +--- +diff --git a/top/top.c b/top/top.c +index 63ec5fe..b4fe21e 100644 +--- a/top/top.c ++++ b/top/top.c +@@ -3939,11 +3939,6 @@ static const char *configs_file (FILE *fp, const char *name, float *delay) { + // too bad fscanf is not as flexible with his format string as snprintf + #error Hey, fix the above fscanf 'PFLAGSSIZ' dependency ! + #endif +- // ensure there's been no manual alteration of fieldscur +- for (n = 0 ; n < EU_MAXPFLGS; n++) { +- if (&w->rc.fieldscur[n] != strrchr(w->rc.fieldscur, w->rc.fieldscur[n])) +- return p; +- } + // be tolerant of missing release 3.3.10 graph modes additions + if (3 > fscanf(fp, "\twinflags=%d, sortindx=%d, maxtasks=%d, graph_cpus=%d, graph_mems=%d\n" + , &w->rc.winflags, &w->rc.sortindx, &w->rc.maxtasks, &w->rc.graph_cpus, &w->rc.graph_mems)) +@@ -3989,6 +3984,11 @@ static const char *configs_file (FILE *fp, const char *name, float *delay) { + return p; + break; + } ++ // ensure there's been no manual alteration of fieldscur ++ for (n = 0 ; n < EU_MAXPFLGS; n++) { ++ if (&w->rc.fieldscur[n] != strrchr(w->rc.fieldscur, w->rc.fieldscur[n])) ++ return p; ++ } + #ifndef USE_X_COLHDR + OFFw(w, NOHIFND_xxx | NOHISEL_xxx); + #endif +-- +2.24.1 + -- cgit v1.2.3
