Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2019-1010204)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to the improper processing of Executable Linkable Format (ELF) files with invalid "e_shoff" header fields in the "gold/fileread.cc:497" and "elfcpp/elfcpp_file.h:644" files. A remote attacker can trick a victim to open a specially crafted ELF file, cause an out-of-bounds read condition and perform a denial of service attack on the target system.
2) Uncontrolled Recursion (CVE-ID: CVE-2021-3530)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to uncontrolled recursion within the demangle_path() function in rust-demangle.c in GNU libiberty. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
3) Buffer overflow (CVE-ID: CVE-2021-3826)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within the dlang_lname() function in d-demangle.c in libiberty. A local user can perform a denial of service (DoS) attack via a crafted mangled symbol.
4) Out-of-bounds write (CVE-ID: CVE-2021-45078)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to a boundary error in stab_xcoff_builtin_type() function in stabs.c. A remote attacker can create a specially crafted file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.
Note, the vulnerability exists due to incorrect patch for #VU13471 (CVE-2018-12699).
5) Uncontrolled Recursion (CVE-ID: CVE-2021-46195)
The vulnerability allows an attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to uncontrolled recursion in the libiberty/rust-demangle.c component. An attacker with ability to pass specially crafted input to the GCC application can consume excessive CPU and memory resources and perform a denial of service (DoS) attack.
6) Resource exhaustion (CVE-ID: CVE-2022-27943)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources within demangle_const in libiberty/rust-demangle.c. A local user can trigger resource exhaustion and perform a denial of service (DoS) attack.
7) Heap-based buffer overflow (CVE-ID: CVE-2022-38533)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within the bfd_getl32() function. A remote attacker can trick the victim to process a specially crafted file, trigger a heap-based buffer overflow and crash the application.
