CVE-2026-40356 (GCVE-0-2026-40356)

Vulnerability from cvelistv5 – Published: 2026-04-28 00:00 – Updated: 2026-04-28 13:10

Summary

In MIT Kerberos 5 (aka krb5) before 1.22.3, there is an integer underflow and resultant out-of-bounds read if an application calls gss_accept_sec_context() on a system with a NegoEx mechanism registered in /etc/gss/mech. An unauthenticated remote attacker can trigger this, possibly causing the process to terminate in parse_message.

Severity

5.9 (Medium)

CVE-2026-39855 (GCVE-0-2026-39855)

Vulnerability from cvelistv5 – Published: 2026-04-09 15:58 – Updated: 2026-04-09 19:22

Title

osslsigncode has an Integer Underflow in PE Page Hash Calculation Can Cause Out-of-Bounds Read

Summary

osslsigncode is a tool that implements Authenticode signing and timestamping. Prior to 2.13, an integer underflow vulnerability exists in osslsigncode version 2.12 and earlier in the PE page-hash computation code (pe_page_hash_calc()). When page hash processing is performed on a PE file, the function subtracts hdrsize from pagesize without first validating that pagesize >= hdrsize. If a malicious PE file sets SizeOfHeaders (hdrsize) larger than SectionAlignment (pagesize), the subtraction underflows and produces a very large unsigned length. The code allocates a zero-filled buffer of pagesize bytes and then attempts to hash pagesize - hdrsize bytes from that buffer. After the underflow, this results in an out-of-bounds read from the heap and can crash the process. The vulnerability can be triggered while signing a malicious PE file with page hashing enabled (-ph), or while verifying a malicious signed PE file that already contains page hashes. Verification of an already signed file does not require the verifier to pass -ph. This vulnerability is fixed in 2.13.

CVE-2026-39314 (GCVE-0-2026-39314)

Vulnerability from cvelistv5 – Published: 2026-04-07 16:59 – Updated: 2026-06-23 15:51

Title

CUPS has an integer underflow in `_ppdCreateFromIPP` causes root cupsd crash via negative `job-password-supported`

Summary

OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. In versions 2.4.16 and prior, an integer underflow vulnerability in _ppdCreateFromIPP() (cups/ppd-cache.c) allows any unprivileged local user to crash the cupsd root process by supplying a negative job-password-supported IPP attribute. The bounds check only caps the upper bound, so a negative value passes validation, is cast to size_t (wrapping to ~2^64), and is used as the length argument to memset() on a 33-byte stack buffer. This causes an immediate SIGSEGV in the cupsd root process. Combined with systemd's Restart=on-failure, an attacker can repeat the crash for sustained denial of service.

Severity

In versions 2.4.16 and prior, an integer underflow vulnerability in _ppdCreateFromIPP() (cups/ppd-cache.c) allows any unprivileged local user to crash the cupsd root process by supplying a negative job-password-supported IPP attribute. The bounds check only caps the upper bound, so a negative value passes validation, is cast to size_t (wrapping to ~2^64), and is used as the length argument to memset() on a 33-byte stack buffer. This causes an immediate SIGSEGV in the cupsd root process. Combined with systemd\u0027s Restart=on-failure, an attacker can repeat the crash for sustained denial of service."

CVE-2026-35049 (GCVE-0-2026-35049)

Vulnerability from cvelistv5 – Published: 2026-06-02 18:35 – Updated: 2026-06-03 13:55

Title

wire-ios has Persistent Remote DoS via Integer Underflow

Summary

wire-ios is an iOS client for the Wire secure messaging application. Prior to version 4.16.0, upon receiving a crafted malicious Proteus external message with an encrypted payload that is shorter than 16 bytes, the Wire iOS client crashes. The crash is triggered automatically after message receival with no user interaction. Since the malicious message persists in the conversation, the app enters a crash loop on relaunch and cannot be reopened until the local state is wiped. This issue has been fixed with version 4.16.0 which introduces the missing length check and is available via the App Store. No known workarounds are available.

Severity

6.5 (Medium)

CVE-2026-34165 (GCVE-0-2026-34165)

Vulnerability from cvelistv5 – Published: 2026-03-31 13:46 – Updated: 2026-04-02 15:10

Title

go-git: Maliciously crafted idx file can cause asymmetric memory consumption

Summary

go-git is an extensible git implementation library written in pure Go. From version 5.0.0 to before version 5.17.1, a vulnerability has been identified in which a maliciously crafted .idx file can cause asymmetric memory consumption, potentially exhausting available memory and resulting in a denial-of-service (DoS) condition. Exploitation requires write access to the local repository's .git directory, it order to create or alter existing .idx files. This issue has been patched in version 5.17.1.

Severity

CVE-2026-34064 (GCVE-0-2026-34064)

Vulnerability from cvelistv5 – Published: 2026-04-22 19:43 – Updated: 2026-04-23 16:25

Title

nimiq-account: Vesting insufficient funds error can panic

Summary

nimiq-account contains account primitives to be used in Nimiq's Rust implementation. Prior to version 1.3.0, `VestingContract::can_change_balance` returns `AccountError::InsufficientFunds` when `new_balance < min_cap`, but it constructs the error using `balance: self.balance - min_cap`. `Coin::sub` panics on underflow, so if an attacker can reach a state where `min_cap > balance`, the node crashes while trying to return an error. The `min_cap > balance` precondition is attacker-reachable because the vesting contract creation data (32-byte format) allows encoding `total_amount` without validating `total_amount <= transaction.value` (the real contract balance). After creating such a vesting contract, the attacker can broadcast an outgoing transaction to trigger the panic during mempool admission and block processing. The patch for this vulnerability is included as part of v1.3.0. No known workarounds are available.

Severity

5.3 (Medium)

Prior to version 1.3.0, `VestingContract::can_change_balance` returns `AccountError::InsufficientFunds` when `new_balance \u003c min_cap`, but it constructs the error using `balance: self.balance - min_cap`. `Coin::sub` panics on underflow, so if an attacker can reach a state where `min_cap \u003e balance`, the node crashes while trying to return an error. The `min_cap \u003e balance` precondition is attacker-reachable because the vesting contract creation data (32-byte format) allows encoding `total_amount` without validating `total_amount \u003c= transaction.value` (the real contract balance). After creating such a vesting contract, the attacker can broadcast an outgoing transaction to trigger the panic during mempool admission and block processing. The patch for this vulnerability is included as part of v1.3.0. No known workarounds are available."

CVE-2026-33999 (GCVE-0-2026-33999)

Vulnerability from cvelistv5 – Published: 2026-04-23 14:53 – Updated: 2026-11-04 22:25

Title

Xorg: xwayland: x.org x server: denial of service via integer underflow in xkb compatibility map handling

Summary

A flaw was found in the X.Org X server. This integer underflow vulnerability, specifically in the XKB compatibility map handling, allows an attacker with local or remote X11 server access to trigger a buffer read overrun. This can lead to memory-safety violations and potentially a denial of service (DoS) or other severe impacts.

Severity

7.8 (High)
