xen: races with evtchn_reset function (XSA-343)

An issue was discovered in Xen through 4.14.x. There are evtchn_reset() race conditions. Uses of EVTCHNOP_reset (potentially by a guest on itself) or XEN_DOMCTL_soft_reset (by itself covered by XSA-77) can lead to the violation of various internal assumptions. This may lead to out of bounds memory accesses or triggering of bug checks. In particular, x86 PV guests may be able to elevate their privilege to that of the host. Host and guest crashes are also possible, leading to a Denial of Service (DoS). Information leaks cannot be ruled out. All Xen versions from 4.5 onwards are vulnerable. Xen versions 4.4 and earlier are not vulnerable.

kernel: Local buffer overflow in ctnetlink_parse_tuple_filter in net/netfilter/nf_conntrack_netlink.c

In the Linux kernel through 5.8.7, local attackers able to inject conntrack netlink configuration could overflow a local buffer, causing crashes or triggering use of incorrect protocol numbers in ctnetlink_parse_tuple_filter in net/netfilter/nf_conntrack_netlink.c, aka CID-1cc5ef91d2ff.

A safety violation was discovered in the rgb crate before 0.8.20 for Rust, leading to (for example) dereferencing of arbitrary pointers or disclosure of uninitialized memory. This occurs because structs can be treated as bytes for read and write operations.

The Kleopatra component before 3.1.12 (and before 20.07.80) for GnuPG allows remote attackers to execute arbitrary code because openpgp4fpr: URLs are supported without safe handling of command-line options. The Qt platformpluginpath command-line option can be used to load an arbitrary DLL.

Mitel MiCloud Management Portal before 6.1 SP5 could allow an attacker, by sending a crafted request, to view system information due to insufficient output sanitization.

An issue was discovered on Gemtek WRTM-127ACN 01.01.02.141 and WRTM-127x9 01.01.02.127 devices. The Monitor Diagnostic network page allows an authenticated attacker to execute a command directly on the target machine. Commands are executed as the root user (uid 0). (Even if a login is required, most routers are left with default credentials.)

lua: buffer overflow in luaO_pushvfstring

Lua through 5.4.0 allows a stack redzone cross in luaO_pushvfstring because a protection mechanism wrongly calls luaD_callnoyield twice in a row.

The decode program in silk-v3-decoder Version:20160922 Build By kn007 does not strictly check data, resulting in a buffer overflow.

speex: stack-based buffer overflow in speexenc.c via a crafted WAV file

A stack buffer overflow in speexenc.c of Speex v1.2 allows attackers to cause a denial of service (DoS) via a crafted WAV file. NOTE: the vendor states "I cannot reproduce it" and it "is a demo program.

When uploading a file in Sysax Multi Server 6.90, an authenticated user can modify the filename="" parameter in the uploadfile_name1.htm form to a length of 368 or more bytes. This will create a buffer overflow condition, causing the application to crash.

IrfanView 4.54 allows a user-mode write access violation starting at FORMATS!ShowPlugInSaveOptions_W+0x0000000000002cba.

nasm: stack-based buffer overflow in stdscan() in stdscan.c

Buffer Overflow vulnerability in scan function in stdscan.c in nasm 2.15rc0 allows remote attackers to cause a denial of service via crafted asm file.

nasm: Heap buffer overflow in hash_findi() in hashtbl.c

Buffer Overflow vulnerability in hash_findi function in hashtbl.c in nasm 2.15rc0 allows remote attackers to cause a denial of service via crafted asm file.

transfig: A global buffer overflow in the put_font in genpict2e.c could result in a denial of service

A global buffer overflow in the put_font in genpict2e.c of fig2dev 3.2.7b allows attackers to cause a denial of service (DOS) via converting a xfig file into pict2e format.

transfig: A global buffer overflow in the shade_or_tint_name_after_declare_color in genpstricks.c could result in a denial of service

A global buffer overflow in the shade_or_tint_name_after_declare_color in genpstricks.c of fig2dev 3.2.7b allows attackers to cause a denial of service (DOS) via converting a xfig file into pstricks format.

transfig: A global buffer overflow in the set_fill component in genge.c could result in a denial of service

A global buffer overflow in the set_fill component in genge.c of fig2dev 3.2.7b allows attackers to cause a denial of service (DOS) via converting a xfig file into ge format.

transfig: A global buffer overflow in the set_color component in genge.c could result in a denial of service

A global buffer overflow in the set_color component in genge.c of fig2dev 3.2.7b allows attackers to cause a denial of service (DOS) via converting a xfig file into ge format.

transfig: A stack-based buffer overflow in the put_arrow() component in genpict2e.c could result in a denial of service

A stack-based buffer overflow in the put_arrow() component in genpict2e.c of fig2dev 3.2.7b allows attackers to cause a denial of service (DOS) via converting a xfig file into pict2e format.

transfig: A global buffer overflow in the genmp_writefontmacro_latex component in genmp.c could result in a denial of service

A global buffer overflow in the genmp_writefontmacro_latex component in genmp.c of fig2dev 3.2.7b allows attackers to cause a denial of service (DOS) via converting a xfig file into mp format.

transfig: A stack-based buffer overflow in the genpstrx_text() component in genpstricks.c could result in a denial of service

A stack-based buffer overflow in the genpstrx_text() component in genpstricks.c of fig2dev 3.2.7b allows attackers to cause a denial of service (DOS) via converting a xfig file into pstricks format.
