GNU : Security Vulnerabilities, CVEs, Published In 2012 (Denial of service) CVSS score >= 4

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 triggers a heap-based buffer overflow.

Multiple integer overflows in the (1) strtod, (2) strtof, (3) strtold, (4) strtod_l, and other unspecified "related functions" in stdlib in GNU C Library (aka glibc or libc6) 2.16 allow local users to cause a denial of service (application crash) and possibly execute arbitrary code via a long string, which triggers a stack-based buffer overflow.

Double free vulnerability in libgnutls in GnuTLS before 3.0.14 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted certificate list.

gnutls_cipher.c in libgnutls in GnuTLS before 2.12.17 and 3.x before 3.0.15 does not properly handle data encrypted with a block cipher, which allows remote attackers to cause a denial of service (heap memory corruption and application crash) via a crafted record, as demonstrated by a crafted GenericBlockCipher structure.

The asn1_get_length_der function in decoding.c in GNU Libtasn1 before 2.12, as used in GnuTLS before 3.0.16 and other products, does not properly handle certain large length values, which allows remote attackers to cause a denial of service (heap memory corruption and application crash) or possibly have unspecified other impact via a crafted ASN.1 structure.

Integer overflow in the GnashImage::size method in libbase/GnashImage.h in GNU Gnash 0.8.10 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted SWF file, which triggers a heap-based buffer overflow.
