Elfutils through version 0.173 is vulnerable to a double-free in the libelf/elfend.c:elfend() function due to the decompression of section data multiple times.. An attacker could exploit this to cause a crash or possibly have unspecified other impact via a crafted ELF.

A vulnerability, which was classified as critical, was found in GNU elfutils 0.192. This affects the function processsymtab of the file readelf.c of the component eu-readelf. The manipulation of the argument D/a leads to buffer overflow. Local access is required to approach this attack. The exploit has been disclosed to the public and may be used. The identifier of the patch is 5e5c0394d82c53e97750fe7b18023e6f84157b81. It is recommended to apply a patch to fix this issue.

A vulnerability was found in GNU elfutils 0.192. It has been declared as critical. Affected by this vulnerability is the function dumpdatasection/printstringsection of the file readelf.c of the component eu-readelf. The manipulation of the argument z/x leads to buffer overflow. An attack has to be approached locally. The exploit has been disclosed to the public and may be used. The identifier of the patch is 73db9d2021cab9e23fd734b0a76a612d52a6f1db. It is recommended to apply a patch to fix this issue.

elfutils 0.170 has a buffer over-read in the ebldynamictagname function of libebl/ebldynamictagname.c because SYMTABSHNDX is unsupported.

Integer overflow in the checksection function in dwarfbeginelf.c in the libdw library, as used in elfutils 0.153 and possibly through 0.158 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a malformed compressed debug section in an ELF file, which triggers a heap-based buffer overflow.

An attempted excessive memory allocation was discovered in the function readlongnames in elfbegin.c in libelf in elfutils 0.174. Remote attackers could leverage this vulnerability to cause a denial-of-service via crafted elf input, which leads to an out-of-memory exception. NOTE: The maintainers believe this is not a real issue, but instead a "warning caused by ASAN because the allocation is big. By setting ASANOPTIONS=allocatormayreturnnull=1 and running the reproducer, nothing happens."

A flaw was found in elfutils through v0.174. An Invalid Memory Address Dereference exists in the function elfend in libelf. Although eu-size is intended to support ar files inside ar files, handlear in size.c closes the outer ar file before handling all inner entries. The vulnerability allows attackers to cause a denial of service (application crash) with a crafted ELF file.

A heap-based buffer over-read was discovered in the function readsrclines in dwarfgetsrclines.c in libdw in elfutils 0.175. A crafted input can cause segmentation faults, leading to denial-of-service, as demonstrated by eu-nm.

Directory traversal vulnerability in the readlongnames function in libelf/elfbegin.c in elfutils 0.152 and 0.161 allows remote attackers to write to arbitrary files to the root directory via a / (slash) in a crafted archive, as demonstrated using the ar program.

A vulnerability has been found in GNU elfutils 0.192 and classified as problematic. This vulnerability affects the function handledynamicsymtab of the file readelf.c of the component eu-read. The manipulation leads to null pointer dereference. Attacking locally is a requirement. The exploit has been disclosed to the public and may be used. The patch is identified as b38e562a4c907e08171c76b8b2def8464d5a104a. It is recommended to apply a patch to fix this issue.

A vulnerability, which was classified as problematic, has been found in GNU elfutils 0.192. This issue affects the function gelfgetsymshndx of the file strip.c of the component eu-strip. The manipulation leads to denial of service. The attack needs to be approached locally. The exploit has been disclosed to the public and may be used. The identifier of the patch is fbf1df9ca286de3323ae541973b08449f8d03aba. It is recommended to apply a patch to fix this issue.

elflint.c in elfutils 0.168 does not validate the number of sections and the number of segments, which allows remote attackers to cause a denial of service (memory consumption) via a crafted ELF file.

elfcompress.c in elfutils 0.168 does not validate the zlib compression factor, which allows remote attackers to cause a denial of service (memory consumption) via a crafted ELF file.

An out-of-bounds read was discovered in elfutils in the way it reads DWARF address ranges information. Function dwarfgetaranges() in dwarfgetaranges.c does not properly check whether it reads beyond the limits of the ELF section. An attacker could use this flaw to cause a denial of service via a crafted file.

Elfutils through version 0.173 is vulnerable to a heap-based buffer over-read due to incorrect checks for the end of attribute lists in the libdw/dwarfgetabbrev.c:libdwgetabbrev() and libdw/dwarfhasattr.c:dwarfhasattr() functions. An attacker could exploit this to cause a crash via a crafted ELF.

In elfutils 0.175, a heap-based buffer over-read was discovered in the function elf32xlatetom in elf32xlatetom.c in libelf. A crafted ELF input can cause a segmentation fault leading to denial of service (program crash) because eblcorenote does not reject malformed core file notes.

An issue was discovered in elfutils 0.175. A segmentation fault can occur in the function elf64xlatetom in libelf/elf32xlatetom.c, due to dwflsegmentreportmodule not checking whether the dyn data read from a core file is truncated. A crafted input can cause a program crash, leading to denial-of-service, as demonstrated by eu-stack.

A flaw was found in elfutils through v0.174. An invalid memory address dereference was discovered in dwflsegmentreportmodule.c in libdwfl. The vulnerability allows attackers to cause a denial of service (application crash) with a crafted ELF file, as demonstrated by considernotes.

In elfutils 0.175, there is a buffer over-read in the eblobjectnote function in eblobjnote.c in libebl. Remote attackers could leverage this vulnerability to cause a denial-of-service via a crafted elf file, as demonstrated by eu-readelf.

In elfutils 0.175, a negative-sized memcpy is attempted in elfcvtnote in libelf/notexlate.h because of an incorrect overflow check. Crafted elf input causes a segmentation fault, leading to denial of service (program crash).
