There's a flaw in binutils 2.46.1 in rsrcprintname() and rsrcparseentries() functions by which an attacker with local access or whom does not have local access but social engineers a victim to run binutils on a crafted PE file, can execute malicious code.

USN-7423-1 fixed several vulnerabilities in GNU. This update provides the corresponding update for Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. Original advisory details: It was discovered that GNU binutils incorrectly handled certain inputs. An attacker could possibly use this issue to cause a crash or execute arbitrary code. (CVE-2025-0840) It was discovered that GNU binutils incorrectly handled certain inputs. An attacker could possibly use this issue to cause a crash, expose sensitive information or execute arbitrary code. (CVE-2025-1153) It was discovered that ld in GNU binutils incorrectly handled certain files. An attacker could possibly use this issue to execute arbitrary code. (CVE-2025-1176)

A vulnerability was found in GNU Binutils 2.43. It has been rated as critical. Affected by this issue is the function bfdputl64 of the file bfd/libbfd.c of the component ld. The manipulation leads to memory corruption. The attack may be launched remotely. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. Upgrading to version 2.44 is able to address this issue. It is recommended to upgrade the affected component. The code maintainer explains, that "[t]his bug has been fixed at some point between the 2.43 and 2.44 releases".

A vulnerability classified as problematic was found in GNU Binutils 2.43/2.44. Affected by this vulnerability is the function bfdsetformat of the file format.c. The manipulation leads to memory corruption. The attack can be launched remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. Upgrading to version 2.45 is able to address this issue. The identifier of the patch is 8d97c1a53f3dc9fd8e1ccdb039b8a33d50133150. It is recommended to upgrade the affected component.

https://www.gnu.org/software/binutils/ nm >=2.43 is affected by: Incorrect Access Control. The type of exploitation is: local. The component is: nm --without-symbol-version function.

An issue was discovered function stabdemanglev3arg in stabs.c in Binutils 2.34 thru 2.38, allows attackers to cause a denial of service due to memory leaks.

GNU Binutils before 2.40 was discovered to contain an excessive memory consumption vulnerability via the function bfddwarf2findnearestlinewithalt at dwarf2.c. The attacker could supply a crafted ELF file and cause a DNS attack.

GNU Binutils before 2.40 was discovered to contain an excessive memory consumption vulnerability via the function loadseparatedebugfiles at dwarf2.c. The attacker could supply a crafted ELF file and cause a DNS attack.

GNU Binutils before 2.34 has an uninitialized-heap vulnerability in function tic4xprintcond (file opcodes/tic4x-dis.c) which could allow attackers to make an information leak.

Heap buffer overflow vulnerability in binutils readelf before 2.40 via function findsectioninset in file readelf.c.

An issue was discovered in binutils libbfd.c 2.36 relating to the auxiliary symbol data allows attackers to read or write to system memory or cause a denial of service.

An issue was discovered function prfunctiontype in prdbg.c in Binutils 2.34 thru 2.38, allows attackers to cause a denial of service due to memory leaks.

An issue was discovered function parsestabstructfields in stabs.c in Binutils 2.34 thru 2.38, allows attackers to cause a denial of service due to memory leaks.

Heap buffer overflow vulnerability in binutils readelf before 2.40 via function displaydebugsection in file readelf.c.

Null pointer dereference vulnerability in Binutils readelf 2.38.50 via function readanddisplayattrvalue in file dwarf.c.

GNU Binutils before 2.40 was discovered to contain a memory leak vulnerability var the function findabstractinstance in dwarf2.c.

An issue was discovered in GNU Binutils 2.34. It is a memory leak when process microblaze-dis.c. This one will consume memory on each insn disassembled.

An issue was discovered function maketempdir, and maketempname in bucomm.c in Binutils 2.34 thru 2.38, allows attackers to cause a denial of service due to memory leaks.

An issue was discovered Binutils objdump before 2.39.3 allows attackers to cause a denial of service or other unspecified impacts via function bfdmachogetsyntheticsymtab in match-o.c.

A memory consumption issue in getdata function in binutils/nm.c in GNU nm before 2.34 allows attackers to cause a denial of service via crafted command.

A potential heap based buffer overflow was found in bfdelfslurpversiontables() in bfd/elf.c. This may lead to loss of availability.

Heap based buffer overflow in binutils-gdb/bfd/libbfd.c in bfdgetl64.

In Binutils, at function bfdinitsectiondecompressstatus, a local variable is supposed to be initialized by function bfdcheckcompressionheader. However, since this function call is inside an else if branch, if the previous if branch is taken, the chtype can be uninitialized and thus directly used to assign sec->compressstatus. Therefore, when the compressstatus field is used in a branch condition, the memory sanitizer aborts.

An illegal memory access flaw was found in the binutils package. Parsing an ELF file containing corrupt symbol version information may result in a denial of service. This issue is the result of an incomplete fix for CVE-2020-16599.

In GNU Binutils before 2.40, there is a heap-buffer-overflow in the error function bfdgetl32 when called from the stripmain function in strip-new via a crafted file.

GCC c++filt v2.26 was discovered to contain a use-after-free vulnerability via the component cplus-dem.c.

There is an open race window when writing output in the following utilities in GNU binutils version 2.35 and earlier:ar, objcopy, strip, ranlib. When these utilities are run as a privileged user (presumably as part of a script updating binaries across different users), an unprivileged user can trick these utilities into getting ownership of arbitrary files through a symlink.
