glibc: Missing unwind info in __startcontext causes infinite loop in _Unwind_Backtrace

The makecontext function in the GNU C Library (aka glibc or libc6) before 2.25 creates execution contexts incompatible with the unwinder on ARM EABI (32-bit) platforms, which might allow context-dependent attackers to cause a denial of service (hang), as demonstrated by applications compiled using gccgo, related to backtrace generation.

mailman: CSRF protection missing in the user options page

Cross-site request forgery (CSRF) vulnerability in the user options page in GNU Mailman 2.1.x before 2.1.23 allows remote attackers to hijack the authentication of arbitrary users for requests that modify an option, as demonstrated by gaining access to the credentials of a victim's account.

wget: files rejected by access list are kept on the disk for the duration of HTTP connection

Race condition in wget 1.17 and earlier, when used in recursive or mirroring mode to download a single file, might allow remote servers to bypass intended access list restrictions by keeping an HTTP connection open.

mailman: Missing CSRF protection in admin web interface

Cross-site request forgery (CSRF) vulnerability in the admin web interface in GNU Mailman before 2.1.15 allows remote attackers to hijack the authentication of administrators.

gnutls: Incorrect certificate validation when using OCSP responses (GNUTLS-SA-2016-3)

The gnutls_ocsp_resp_check_crt function in lib/x509/ocsp.c in GnuTLS before 3.4.15 and 3.5.x before 3.5.4 does not verify the serial length of an OCSP response, which might allow remote attackers to bypass an intended certificate validation mechanism via vectors involving trailing bytes left by gnutls_malloc.

GNU Binutils ld elflink.c _bfd_elf_gc_mark_rsec heap-based overflow

A vulnerability was found in GNU Binutils 2.43 and classified as critical. This issue affects the function _bfd_elf_gc_mark_rsec of the file elflink.c of the component ld. The manipulation leads to heap-based buffer overflow. The attack may be initiated remotely. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. The patch is named f9978defb6fab0bd8583942d97c112b0932ac814. It is recommended to apply a patch to fix this issue.

libmicrohttpd: stack overflow in MHD_digest_auth_check()

Stack-based buffer overflow in the MHD_digest_auth_check function in libmicrohttpd before 0.9.32, when MHD_OPTION_CONNECTION_MEMORY_LIMIT is set to a large value, allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long URI in an authentication header.

libmicrohttpd: out-of-bounds read in MHD_http_unescape()

The MHD_http_unescape function in libmicrohttpd before 0.9.32 might allow remote attackers to obtain sensitive information or cause a denial of service (crash) via unspecified vectors that trigger an out-of-bounds read.

glibc: PTR_MANGLE does not initialize to a random value for the pointer guard when compiling static executables

The PTR_MANGLE implementation in the GNU C Library (aka glibc or libc6) 2.4, 2.17, and earlier, and Embedded GLIBC (EGLIBC) does not initialize the random value for the pointer guard, which makes it easier for context-dependent attackers to control execution flow by leveraging a buffer-overflow vulnerability in an application and using the known zero value pointer guard to calculate a pointer address.

gnutls: dane_query_tlsa() CVE-2013-4466 fix off-by-one

Off-by-one error in the dane_raw_tlsa in the DANE library (libdane) in GnuTLS 3.1.x before 3.1.16 and 3.2.x before 3.2.6 allows remote servers to cause a denial of service (memory corruption) via a response with more than four DANE entries. NOTE: this issue is due to an incomplete fix for CVE-2013-4466.

gnutls: dane_query_tlsa() buffer overflow (GNUTLS-SA-2013-3)

Buffer overflow in the dane_query_tlsa function in the DANE library (libdane) in GnuTLS 3.1.x before 3.1.15 and 3.2.x before 3.2.5 allows remote servers to cause a denial of service (memory corruption) via a response with more than four DANE entries.

glibc: Stack (frame) overflow in getaddrinfo() when called with AF_INET6

Stack-based buffer overflow in the getaddrinfo function in sysdeps/posix/getaddrinfo.c in GNU C Library (aka glibc or libc6) 2.18 and earlier allows remote attackers to cause a denial of service (crash) via a (1) hostname or (2) IP address that triggers a large number of AF_INET6 address results. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-1914.

glibc: three integer overflows in memory allocator

Multiple integer overflows in malloc/malloc.c in the GNU C Library (aka glibc or libc6) 2.18 and earlier allow context-dependent attackers to cause a denial of service (heap corruption) via a large value to the (1) pvalloc, (2) valloc, (3) posix_memalign, (4) memalign, or (5) aligned_alloc functions.

glibc: Buffer overwrite when using readdir_r on file systems returning file names longer than NAME_MAX characters

sysdeps/posix/readdir_r.c in the GNU C Library (aka glibc or libc6) 2.18 and earlier allows context-dependent attackers to cause a denial of service (out-of-bounds write and crash) or possibly execute arbitrary code via a crafted (1) NTFS or (2) CIFS image.

cyrus-sasl: NULL pointer dereference (DoS) when glibc v.2.17 or FIPS-140 enabled Linux system used

Cyrus SASL 2.1.23, 2.1.26, and earlier does not properly handle when a NULL value is returned upon an error by the crypt function as implemented in glibc 2.17 and later, which allows remote attackers to cause a denial of service (thread crash and consumption) via (1) an invalid salt or, when FIPS-140 is enabled, a (2) DES or (3) MD5 encrypted password, which triggers a NULL pointer dereference.

(32-bit): Multiple integer overflows in the printf implementation

Multiple integer overflows in the strfmon implementation in the GNU C Library (aka glibc or libc6) 2.10.1 and earlier allow context-dependent attackers to cause a denial of service (memory consumption or application crash) via a crafted format string, as demonstrated by a crafted first argument to the money_format function in PHP, a related issue to CVE-2008-1391.

libiberty: integer overflow, leading to heap-buffer overflow by processing certain file headers via bfd binary

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.

glibc: svc_run() produces high cpu usage when accept() fails with EMFILE error

The svc_run function in the RPC implementation in glibc before 2.15 allows remote attackers to cause a denial of service (CPU consumption) via a large number of RPC connections.

gdb: object file .debug_gdb_scripts section improper input validation

GNU Project Debugger (GDB) before 7.5, when .debug_gdb_scripts is defined, automatically loads certain files from the current working directory, which allows local users to gain privileges via crafted files such as Python scripts.

plugin/npapi/plugin.cpp in Gnash before 0.8.10 uses weak permissions (world readable) for cookie files with predictable names in /tmp, which allows local users to obtain sensitive information.
