Astra Linux – Vulnerability in binutils

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

Astra Linux – Vulnerability in binutils

There is a flaw in the binutils within bfd/pef.c. An attacker who can submit a crafted PEF file for parsing by objdump could cause a heap buffer overflow, leading to out-of-bounds reads, which could result in a disruption to the application’s functionality. This flaw affects binutils versions pri...

Astra Linux – Vulnerability in binutils

A issue was discovered in cp-demangle.c within GNU libiberty, as part of the GNU Binutils 2.31 package. This issue involves stack exhaustion during the C++ demangling functions provided by libiberty. There is also a stack consumption problem caused by recursive stack frames: cplusdemangletype,...

Astra Linux – Vulnerability in binutils

A issue was discovered in the Binary File Descriptor BFD library also known as libbfd, as distributed in GNU Binutils 2.32. There is a heap-based buffer over-read in bfddoprnt in bfd.c, due to elfobjectp in elfcode.h improperly handling the eshstrndx section of type SHTGROUP by omitting a trailin...

Astra Linux – Vulnerability in binutils

The getcount function in cplus-dem.c in GNU libiberty, as distributed in GNU Binutils 2.31, allows remote attackers to cause a denial of service malloc calls with an integer overflow result or potentially have unspecified other impacts through a crafted string, as demonstrated by c++filt...

Astra Linux – Vulnerability in binutils

The bfdgenericreadminisymbols function in syms.c within the Binary File Descriptor BFD library also known as libbfd, as part of GNU Binutils 2.31, contains a memory leak that can occur due to an improperly crafted ELF file. This leads to a denial of service condition due to excessive memory...

Astra Linux – Vulnerability in binutils

A heap-based buffer overflow issue was discovered in the secmergehashlookup function in merge.c within the Binary File Descriptor BFD library also known as libbfd, as part of the GNU Binutils 2.31. This issue arises due to bfdaddmergesection improperly handling section merges when the size is not...
