An issue was discovered in GitLab Community and Enterprise Edition 11 through 12.4 when building Nested GraphQL queries. It has a large or infinite loop.

ProFTPD before 1.3.6b and 1.3.7rc before 1.3.7rc2 allows remote unauthenticated denial-of-service due to incorrect handling of overly long commands because main.c in a child process enters an infinite loop.

Denial of service

Improper Check for filenames with overly long extensions in PostMaster (sending in email) or uploading files (e.g. attaching files to mails) of ((OTRS)) Community Edition and OTRS allows an remote attacker to cause an endless loop. This issue affects: OTRS AG: ((OTRS)) Community Edition 5.0.x version 5.0.38 and prior versions; 6.0.x version 6.0.23 and prior versions. OTRS AG: OTRS 7.0.x version 7.0.12 and prior versions.

xen: Unlimited Arm Atomics Operations (XSA-295)

An issue was discovered in Xen through 4.12.x allowing Arm domU attackers to cause a denial of service (infinite loop) involving a compare-and-exchange operation.

xen: Unlimited Arm Atomics Operations (XSA-295)

An issue was discovered in Xen through 4.12.x allowing Arm domU attackers to cause a denial of service (infinite loop) involving a LoadExcl or StoreExcl operation.

kernel: i_size_read() infinite loop leads to denial of service

An issue was discovered in the Linux kernel before 5.0.4. The 9p filesystem did not protect i_size_write() properly, which causes an i_size_read() infinite loop and denial of service on SMP systems.

wireshark: gryphon dissector infinite loop (wnpa-sec-2019-21)

In Wireshark 3.0.0 to 3.0.3 and 2.6.0 to 2.6.10, the Gryphon dissector could go into an infinite loop. This was addressed in plugins/epan/gryphon/packet-gryphon.c by checking for a message length of zero.

In the TCP implementation (gnrc_tcp) in RIOT through 2019.07, the parser for TCP options does not terminate on all inputs, allowing a denial-of-service, because sys/net/gnrc/transport_layer/tcp/gnrc_tcp_option.c has an infinite loop for an unknown zero-length option.

In DjVuLibre 3.5.27, the bitmap reader component allows attackers to cause a denial-of-service error (resource exhaustion caused by a GBitmap::read_rle_raw infinite loop) by crafting a corrupted image file, related to libdjvu/DjVmDir.cpp and libdjvu/GBitmap.cpp.

edk2: DxeImageVerificationHandler integer overflow leads to endless loop

Integer overflow in DxeImageVerificationHandler() EDK II may allow an authenticated user to potentially enable denial of service via local access.

In mpc8_read_header in libavformat/mpc8.c in Libav 12.3, an input file can result in an avio_seek infinite loop and hang, with 100% CPU consumption. Attackers could leverage this vulnerability to cause a denial of service via a crafted file.

In Libav 12.3, there is an infinite loop in the function wv_read_block_header() in the file wvdec.c.

An issue was discovered in Libav 12.3. There is an infinite loop in the function mov_probe in the file libavformat/mov.c, related to offset and tag.

haproxy: DoS via vectors realted to htx_manage_client_side_cookies in proto_htx.c

HAProxy through 2.0.2 allows attackers to cause a denial of service (ha_panic) via vectors related to htx_manage_client_side_cookies in proto_htx.c.

An issue was discovered in Foxit PhantomPDF before 8.3.11. The application could crash when calling the clone function due to an endless loop resulting from confusing relationships between a child and parent object (caused by an append error).

Zipios before 0.1.7 does not properly handle certain malformed zip archives and can go into an infinite loop, causing a denial of service. This is related to zipheadio.h:readUint32() and zipfile.cpp:Zipfile::Zipfile().

apache-commons-compress: Infinite loop in name encoding algorithm

The file name encoding algorithm used internally in Apache Commons Compress 1.15 to 1.18 can get into an infinite loop when faced with specially crafted inputs. This can lead to a denial of service attack if an attacker can choose the file names inside of an archive created by Compress.

qemu: scsi: lsi: potential infinite loop when executing script in lsi_execute_script

In QEMU 1:4.1-1, 1:2.1+dfsg-12+deb8u6, 1:2.8+dfsg-6+deb9u8, 1:3.1+dfsg-8~deb10u1, 1:3.1+dfsg-8+deb10u2, and 1:2.1+dfsg-12+deb8u12 (fixed), when executing script in lsi_execute_script(), the LSI scsi adapter emulator advances 's->dsp' index to read next opcode. This can lead to an infinite loop if the next opcode is empty. Move the existing loop exit after 10k iterations so that it covers no-op opcodes as well.

wireshark: Rbm dissector infinite loop (wnpa-sec-2019-13)

In Wireshark 3.0.0, the Rbm dissector could go into an infinite loop. This was addressed in epan/dissectors/file-rbm.c by handling unknown object types safely.

wireshark: GSUP dissector infinite loop (wnpa-sec-2019-18)

In Wireshark 3.0.0, the GSUP dissector could go into an infinite loop. This was addressed in epan/dissectors/packet-gsm_gsup.c by rejecting an invalid Information Element length.
