CVE-2019-3813 4 Canonical, Debian, Redhat and 1 more 9 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 6 more 2026-06-17 5.4 MEDIUM 7.5 HIGH
Spice, versions 0.5.2 through 0.14.1, are vulnerable to an out-of-bounds read due to an off-by-one error in memslot_get_virt. This may lead to a denial of service, or, in the worst case, code-execution by unauthenticated attackers.
CVE-2019-18423 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2026-06-17 8.5 HIGH 8.8 HIGH
An issue was discovered in Xen through 4.12.x allowing ARM guest OS users to cause a denial of service via a XENMEM_add_to_physmap hypercall. p2m->max_mapped_gfn is used by the functions p2m_resolve_translation_fault() and p2m_get_entry() to sanity check guest physical frame. The rest of the code in the two functions will assume that there is a valid root table and check that with BUG_ON(). The function p2m_get_root_pointer() will ignore the unused top bits of a guest physical frame. This means that the function p2m_set_entry() will alias the frame. However, p2m->max_mapped_gfn will be updated using the original frame. It would be possible to set p2m->max_mapped_gfn high enough to cover a frame that would lead p2m_get_root_pointer() to return NULL in p2m_get_entry() and p2m_resolve_translation_fault(). Additionally, the sanity check on p2m->max_mapped_gfn is off-by-one allowing "highest mapped + 1" to be considered valid. However, p2m_get_root_pointer() will return NULL. The problem could be triggered with a specially crafted hypercall XENMEM_add_to_physmap{, _batch} followed by an access to an address (via hypercall or direct access) that passes the sanity check but cause p2m_get_root_pointer() to return NULL. A malicious guest administrator may cause a hypervisor crash, resulting in a Denial of Service (DoS). Xen version 4.8 and newer are vulnerable. Only Arm systems are vulnerable. x86 systems are not affected.
CVE-2019-14532 2 Fedoraproject, Sleuthkit 2 Fedora, The Sleuth Kit 2026-06-17 7.5 HIGH 9.8 CRITICAL
An issue was discovered in The Sleuth Kit (TSK) 4.6.6. There is an off-by-one overwrite due to an underflow on tools/hashtools/hfind.cpp while using a bogus hash table.
CVE-2019-14323 1 Simple Service Discovery Protocol Responder Project 1 Simple Service Discovery Protocol Responder 2026-06-17 5.0 MEDIUM 7.5 HIGH
SSDP Responder 1.x through 1.5 mishandles incoming network messages, leading to a stack-based buffer overflow by 1 byte. This results in a crash of the server, but only when strict stack checking is enabled. This is caused by an off-by-one error in ssdp_recv in ssdpd.c.
CVE-2019-13306 4 Canonical, Debian, Imagemagick and 1 more 4 Ubuntu Linux, Debian Linux, Imagemagick and 1 more 2026-06-17 6.8 MEDIUM 7.8 HIGH
ImageMagick 7.0.8-50 Q16 has a stack-based buffer overflow at coders/pnm.c in WritePNMImage because of off-by-one errors.
CVE-2019-13305 4 Canonical, Debian, Imagemagick and 1 more 4 Ubuntu Linux, Debian Linux, Imagemagick and 1 more 2026-06-17 6.8 MEDIUM 7.8 HIGH
ImageMagick 7.0.8-50 Q16 has a stack-based buffer overflow at coders/pnm.c in WritePNMImage because of a misplaced strncpy and an off-by-one error.
CVE-2019-12521 4 Canonical, Debian, Opensuse and 1 more 4 Ubuntu Linux, Debian Linux, Leap and 1 more 2026-06-17 4.3 MEDIUM 5.9 MEDIUM
An issue was discovered in Squid through 4.7. When Squid is parsing ESI, it keeps the ESI elements in ESIContext. ESIContext contains a buffer for holding a stack of ESIElements. When a new ESIElement is parsed, it is added via addStackElement. addStackElement has a check for the number of elements in this buffer, but it's off by 1, leading to a Heap Overflow of 1 element. The overflow is within the same structure so it can't affect adjacent memory blocks, and thus just leads to a crash while processing.
CVE-2019-10131 5 Canonical, Debian, Imagemagick and 2 more 5 Ubuntu Linux, Debian Linux, Imagemagick and 2 more 2026-06-17 3.6 LOW 7.1 HIGH
An off-by-one read vulnerability was discovered in ImageMagick before version 7.0.7-28 in the formatIPTCfromBuffer function in coders/meta.c. A local attacker may use this flaw to read beyond the end of the buffer or to crash the program.
CVE-2018-9860 1 Botan Project 1 Botan 2026-06-17 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Botan 1.11.32 through 2.x before 2.6.0. An off-by-one error when processing malformed TLS-CBC ciphertext could cause the receiving side to include in the HMAC computation exactly 64K bytes of data following the record buffer, aka an over-read. The MAC comparison will subsequently fail and the connection will be closed. This could be used for denial of service. No information leak occurs.
CVE-2018-8828 2 Debian, Kamailio 2 Debian Linux, Kamailio 2026-06-17 7.5 HIGH 9.8 CRITICAL
A Buffer Overflow issue was discovered in Kamailio before 4.4.7, 5.0.x before 5.0.6, and 5.1.x before 5.1.2. A specially crafted REGISTER message with a malformed branch or From tag triggers an off-by-one heap-based buffer overflow in the tmx_check_pretran function in modules/tmx/tmx_pretran.c.
CVE-2018-7329 1 Wireshark 1 Wireshark 2026-06-17 5.0 MEDIUM 7.5 HIGH
In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12, epan/dissectors/packet-s7comm.c had an infinite loop that was addressed by correcting off-by-one errors.
CVE-2018-5800 4 Canonical, Debian, Libraw and 1 more 6 Ubuntu Linux, Debian Linux, Libraw and 3 more 2026-06-17 4.3 MEDIUM 6.5 MEDIUM
An off-by-one error within the "LibRaw::kodak_ycbcr_load_raw()" function (internal/dcraw_common.cpp) in LibRaw versions prior to 0.18.7 can be exploited to cause a heap-based buffer overflow and subsequently cause a crash.
CVE-2018-14682 5 Cabextract, Cabextract Project, Canonical and 2 more 8 Libmspack, Cabextract, Ubuntu Linux and 5 more 2026-06-17 6.8 MEDIUM 8.8 HIGH

An issue was discovered in mspack/chmd.c in libmspack before 0.7alpha. There is an off-by-one error in the CHM PMGI/PMGL chunk number validity checks, which could lead to denial of service (uninitialized data dereference and application crash).
CVE-2018-14599 5 Canonical, Debian, Fedoraproject and 2 more 7 Ubuntu Linux, Debian Linux, Fedora and 4 more 2026-06-17 7.5 HIGH 9.8 CRITICAL
An issue was discovered in libX11 through 1.6.5. The function XListExtensions in ListExt.c is vulnerable to an off-by-one error caused by malicious server responses, leading to DoS or possibly unspecified other impact.
CVE-2017-9720 1 Google 1 Android 2026-06-17 6.8 MEDIUM 7.8 HIGH
In all Qualcomm products with Android releases from CAF using the Linux kernel, due to an off-by-one error in a camera driver, an out-of-bounds read/write can occur.
CVE-2017-2618 3 Debian, Linux, Redhat 8 Debian Linux, Linux Kernel, Enterprise Linux and 5 more 2026-06-17 4.9 MEDIUM 5.5 MEDIUM
A flaw was found in the Linux kernel's handling of clearing SELinux attributes on /proc/pid/attr files before 4.9.10. An empty (null) write to this file can crash the system by causing the system to attempt to access unmapped kernel memory.
CVE-2017-14502 1 Libarchive 1 Libarchive 2026-06-17 5.0 MEDIUM 7.5 HIGH
read_header in archive_read_support_format_rar.c in libarchive 3.3.2 suffers from an off-by-one error for UTF-16 names in RAR archives, leading to an out-of-bounds read in archive_read_format_rar_read_header.
