GNU : Security Vulnerabilities, CVEs, Published In 2006 (Overflow)

Stack-based buffer overflow in the ps_gettext function in ps.c for GNU gv 3.6.2, and possibly earlier versions, allows user-assisted attackers to execute arbitrary code via a PostScript (PS) file with certain headers that contain long comments, as demonstrated using the (1) DocumentMedia, (2) DocumentPaperSizes, and possibly (3) PageMedia and (4) PaperSize headers. NOTE: this issue can be exploited through other products that use gv such as evince.

Buffer overflow in the readline function in util/texindex.c, as used by the (1) texi2dvi and (2) texindex commands, in texinfo 4.8 and earlier allows local users to execute arbitrary code via a crafted Texinfo file.

Buffer overflow in the (1) DWARF (dwarfread.c) and (2) DWARF2 (dwarf2read.c) debugging code in GNU Debugger (GDB) 6.5 allows user-assisted attackers, or restricted users, to execute arbitrary code via a crafted file with a location block (DW_FORM_block) that contains a large number of operations.

Buffer overflow in getsym in tekhex.c in libbfd in Free Software Foundation GNU Binutils before 20060423, as used by GNU strings, allows context-dependent attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a file with a crafted Tektronix Hex Format (TekHex) record in which the length character is not a valid hexadecimal character.

fold_binary in fold-const.c in GNU Compiler Collection (gcc) 4.1 improperly handles pointer overflow when folding a certain expr comparison to a corresponding offset comparison in cases other than EQ_EXPR and NE_EXPR, which might introduce buffer overflow vulnerabilities into applications that could be exploited by context-dependent attackers.NOTE: the vendor states that the essence of the issue is "not correctly interpreting an offset to a pointer as a signed value."

Buffer overflow in tar 1.14 through 1.15.90 allows user-assisted attackers to cause a denial of service (application crash) and possibly execute code via unspecified vectors involving PAX extended headers.
