Gnu Gcc vulnerabilities

CVE-2023-4039 [MEDIUM] CWE-693 CVE-2023-4039: **DISPUTED**A failure in the -fstack-protector feature in GCC-based toolchains that target AArch64 **DISPUTED**A failure in the -fstack-protector feature in GCC-based toolchains that target AArch64 allows an attacker to exploit an existing buffer overflow in dynamically-sized local variables in your application without this being detected. This stack-protector failure only applies to C99-style dynamically-sized local variables or those created using

CVE-2021-3826 [MEDIUM] CWE-119 CVE-2021-3826: Heap/stack buffer overflow in the dlang_lname function in d-demangle.c in libiberty allows attackers Heap/stack buffer overflow in the dlang_lname function in d-demangle.c in libiberty allows attackers to potentially cause a denial of service (segmentation fault and crash) via a crafted mangled symbol.

CVE-2022-27943 [MEDIUM] CWE-674 CVE-2022-27943: libiberty/rust-demangle.c in GNU GCC 11.2 allows stack consumption in demangle_const, as demonstrate libiberty/rust-demangle.c in GNU GCC 11.2 allows stack consumption in demangle_const, as demonstrated by nm-new.

CVE-2021-46195 [MEDIUM] CWE-674 CVE-2021-46195: GCC v12.0 was discovered to contain an uncontrolled recursion via the component libiberty/rust-deman GCC v12.0 was discovered to contain an uncontrolled recursion via the component libiberty/rust-demangle.c. This vulnerability allows attackers to cause a Denial of Service (DoS) by consuming excessive CPU and memory resources.

CVE-2021-37322 [HIGH] CWE-416 CVE-2021-37322: GCC c++filt v2.26 was discovered to contain a use-after-free vulnerability via the component cplus-d GCC c++filt v2.26 was discovered to contain a use-after-free vulnerability via the component cplus-dem.c.

CVE-2002-2439 [HIGH] CWE-190 CVE-2002-2439: Integer overflow in the new[] operator in gcc before 4.8.0 allows attackers to have unspecified impa Integer overflow in the new[] operator in gcc before 4.8.0 allows attackers to have unspecified impacts.

CVE-2019-15847 [HIGH] CWE-331 CVE-2019-15847: The POWER9 backend in GNU Compiler Collection (GCC) before version 10 could optimize multiple calls The POWER9 backend in GNU Compiler Collection (GCC) before version 10 could optimize multiple calls of the __builtin_darn intrinsic into a single call, thus reducing the entropy of the random number generator. This occurred because a volatile operation was not specified. For example, within a single execution of a program, the output of every __builtin

CVE-2018-12886 [HIGH] CWE-209 CVE-2018-12886: stack_protect_prologue in cfgexpand.c and stack_protect_epilogue in function.c in GNU Compiler Colle stack_protect_prologue in cfgexpand.c and stack_protect_epilogue in function.c in GNU Compiler Collection (GCC) 4.1 through 8 (under certain circumstances) generate instruction sequences when targeting ARM targets that spill the address of the stack protector guard, which allows an attacker to bypass the protection of -fstack-protector, -fstack-protec

CVE-2017-11671 [MEDIUM] CWE-338 CVE-2017-11671: Under certain circumstances, the ix86_expand_builtin function in i386.c in GNU Compiler Collection ( Under certain circumstances, the ix86_expand_builtin function in i386.c in GNU Compiler Collection (GCC) version 4.6, 4.7, 4.8, 4.9, 5 before 5.5, and 6 before 6.4 will generate instruction sequences that clobber the status flag of the RDRAND and RDSEED intrinsics before it can be read, potentially causing failures of these instructions to go unrepo

CVE-2015-5276 [MEDIUM] CWE-200 CVE-2015-5276: The std::random_device class in libstdc++ in the GNU Compiler Collection (aka GCC) before 4.9.4 does The std::random_device class in libstdc++ in the GNU Compiler Collection (aka GCC) before 4.9.4 does not properly handle short reads from blocking sources, which makes it easier for context-dependent attackers to predict the random values via unspecified vectors.

CVE-2008-1685 [MEDIUM] CWE-119 CVE-2008-1685: gcc 4.2.0 through 4.3.0 in GNU Compiler Collection, when casts are not used, considers the sum of a gcc 4.2.0 through 4.3.0 in GNU Compiler Collection, when casts are not used, considers the sum of a pointer and an int to be greater than or equal to the pointer, which might lead to removal of length testing code that was intended as a protection mechanism against integer overflow and buffer overflow attacks, and provide no diagnostic message about th

CVE-2008-1367 [HIGH] CWE-399 CVE-2008-1367: gcc 4.3.x does not generate a cld instruction while compiling functions used for string manipulation gcc 4.3.x does not generate a cld instruction while compiling functions used for string manipulation such as memcpy and memmove on x86 and i386, which can prevent the direction flag (DF) from being reset in violation of ABI conventions and cause data to be copied in the wrong direction during signal handling in the Linux kernel, which might allow contex

CVE-2006-1902 [LOW] CWE-119 CVE-2006-1902: fold_binary in fold-const.c in GNU Compiler Collection (gcc) 4.1 improperly handles pointer overflow 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 v

CVE-2000-1219 [HIGH] CVE-2000-1219: The -ftrapv compiler option in gcc and g++ 3.3.3 and earlier does not handle all types of integer ov The -ftrapv compiler option in gcc and g++ 3.3.3 and earlier does not handle all types of integer overflows, which may leave applications vulnerable to vulnerabilities related to overflows.
