Vulnerabilidades

The demangle_template_value_parm and do_hpacc_template_literal functions in cplus-dem.c in libiberty allow remote attackers to cause a denial of service (out-of-bounds read and crash) via a crafted binary.

Buffer overflow in the do_type function in cplus-dem.c in libiberty allows remote attackers to cause a denial of service (segmentation fault and crash) via a crafted binary.

The d_print_comp function in cp-demangle.c in libiberty allows remote attackers to cause a denial of service (segmentation fault and crash) via a crafted binary, which triggers infinite recursion and a buffer overflow, related to a node having "itself as ancestor more than once."

Integer overflow in cp-demangle.c in libiberty allows remote attackers to cause a denial of service (segmentation fault and crash) via a crafted binary, related to inconsistent use of the long and int types for lengths.

Integer overflow in the gnu_special function in libiberty allows remote attackers to cause a denial of service (segmentation fault and crash) via a crafted binary, related to the "demangling of virtual tables."

Use-after-free vulnerability in libiberty allows remote attackers to cause a denial of service (segmentation fault and crash) via a crafted binary, related to "ktypevec."

Use-after-free vulnerability in libiberty allows remote attackers to cause a denial of service (segmentation fault and crash) via a crafted binary, related to "btypevec."

Integer overflow in the string_appends function in cplus-dem.c in libiberty allows remote attackers to execute arbitrary code via a crafted executable, which triggers a buffer overflow.

The demangler in GNU Libiberty allows remote attackers to cause a denial of service (infinite loop, stack overflow, and crash) via a cycle in the references of remembered mangled types.

Multiple integer overflows in the (1) _objalloc_alloc function in objalloc.c and (2) objalloc_alloc macro in include/objalloc.h in GNU libiberty, as used by binutils 2.22, allow remote attackers to cause a denial of service (crash) via vectors related to the "addition of CHUNK_HEADER_SIZE to the length," which…
