graphviz: buffer overflow in the graph parser

Stack-based buffer overflow in the push_subg function in parser.y (lib/graph/parser.c) in Graphviz 2.20.2, and possibly earlier versions, allows user-assisted remote attackers to cause a denial of service (memory corruption) or execute arbitrary code via a DOT file with a large number of Agraph_t elements.

graphviz before 2.2.1 allows local users to overwrite arbitrary files via a symlink attack on temporary files. NOTE: this issue was originally associated with a different CVE identifier, CVE-2005-2965, which had been used for multiple different issues. This is the correct identifier.

Graphviz 2.36.0 through 9.x before 10.0.1 has an out-of-bounds read via a crafted config6a file. NOTE: exploitability may be uncommon because this file is typically owned by root.

graphviz: buffer overflow in yyerror() due to improper fix for CVE-2014-0978

Stack-based buffer overflow in the "yyerror" function in Graphviz 2.34.0 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted file. NOTE: This vulnerability exists due to an incomplete fix for CVE-2014-0978.

graphviz: format string vulnerability in yyerror()

Format string vulnerability in the yyerror function in lib/cgraph/scan.l in Graphviz allows remote attackers to have unspecified impact via format string specifiers in unknown vectors, which are not properly handled in an error string.

graphviz: stack-based buffer overflow in yyerror()

Stack-based buffer overflow in the yyerror function in lib/cgraph/scan.l in Graphviz 2.34.0 allows remote attackers to have unspecified impact via a long line in a dot file.

graphviz: stack-based buffer overflow in chkNum()

Stack-based buffer overflow in the chkNum function in lib/cgraph/scan.l in Graphviz 2.34.0 allows remote attackers to have unspecified impact via vectors related to a "badly formed number" and a "long digit list."

graphviz: off-by-one in parse_reclbl() in lib/common/shapes.c

Buffer Overflow in Graphviz Graph Visualization Tools from commit ID f8b9e035 and earlier allows remote attackers to execute arbitrary code or cause a denial of service (application crash) by loading a crafted file into the "lib/common/shapes.c" component.

graphviz: recursive function call in agclose in lib\cgraph\graph.c causing stack consumption

An issue was discovered in lib\cdt\dttree.c in libcdt.a in graphviz 2.40.1. Stack consumption occurs because of recursive agclose calls in lib\cgraph\graph.c in libcgraph.a, related to agfstsubg in lib\cgraph\subg.c.

graphviz: null pointer dereference in function agroot() in cgraph\obj.c

The agroot() function in cgraph\obj.c in libcgraph.a in Graphviz 2.39.20160612.1140 has a NULL pointer dereference, as demonstrated by graphml2gv.

graphviz: NULL pointer dereference in rebuild_vlis

NULL pointer dereference vulnerability in the rebuild_vlists function in lib/dotgen/conc.c in the dotgen library in Graphviz 2.40.1 allows remote attackers to cause a denial of service (application crash) via a crafted file.
