Heap-based buffer overflow (CWE-122) in HP's HPLIP - the HP Linux Imaging and Printing Software stack shipped as the default printer/scanner driver on most Linux distributions - can be triggered when attacker-influenced data is processed by a vulnerable component, potentially leading to remote code execution, privilege escalation, denial of service, information disclosure, or unauthorized file modification. This is a bundled advisory covering multiple externally reported flaws across several HPLIP components, so the precise prerequisites vary per sub-vulnerability; the vendor assigns CVSS 4.0 score 9.3 (Critical) with a remote, unauthenticated, low-complexity vector, while the independent assessment is more conservative at CVSS 3.1 AV:N/AC:H/PR:N/UI:N, reflecting that the system must be running HPLIP and actually process malicious input. No public exploit code and no confirmed active exploitation were identified at time of analysis.
HPLIP (HP Linux Imaging and Printing Software) is affected by multiple heap-based buffer overflow vulnerabilities (CWE-122) that can lead to remote code execution, privilege escalation, denial of service, information disclosure, or unauthorized file modification. Exploitation requires user interaction, such as a victim performing a print or scan operation or processing attacker-supplied imaging data, but no authentication is needed, and the attack is network-reachable. HP has remediated the issues; no public exploit code has been identified at the time of analysis.
Heap-based buffer overflow and related memory-safety flaws in HP Linux Imaging and Printing (HPLIP) can allow remote code execution, privilege escalation, denial of service, information disclosure, or unauthorized file modification on Linux hosts where HPLIP is installed and the affected component is active. This is an aggregate HP bulletin (hpsbpi04151) that bundles multiple externally reported issues under one CVE, so the published CVSS 4.0 score of 9.3 (AV:N/AC:L/PR:N/UI:N/VC:H/VI:H/VA:H) represents the worst-case component rather than any single flaw, and the assessed CVSS 3.1 score is lower (AV:N/AC:H) because several sub-issues are more likely local than remote and heap exploitation requires reliable memory grooming. No public exploit code or confirmed active exploitation was identified at time of analysis, and the exposure is limited to Linux systems on which HPLIP is deployed rather than being a universal service.
Command injection weaknesses in HP Linux Imaging and Printing Software (HPLIP) allow a local attacker to execute arbitrary operating-system commands with the privileges of the affected HPLIP component, resulting in high confidentiality, integrity, and availability impact (vendor CVSS 4.0 base 8.4) and spanning remote code execution, privilege escalation, denial of service, information disclosure, and unauthorized file modification. Exploitation is not remote: it requires local access to a Linux host that has HPLIP installed and in use, and it requires active user interaction, typically by inducing a legitimate user to feed attacker-controlled input into a vulnerable HPLIP component that builds an OS command (CWE-78). No authentication or elevated privileges are needed (PR:N), and no public exploit code or confirmed active exploitation was identified at time of analysis; HP has released remediation for the affected components in advisory HPSBPI04151.
Heap-based buffer overflows and related memory-safety flaws in HPLIP (HP Linux Imaging and Printing Software) let remote attackers corrupt memory in the print, scan, and device-discovery stack, potentially yielding remote code execution, privilege escalation, denial of service, information disclosure, or unauthorized file modification. Only Linux hosts with HPLIP installed and actively processing attacker-influenced input - a crafted print job, a rogue printer/scanner response, or a file handled by the HPLIP stack - are affected, and exploitation is gated on active user interaction (initiating or accepting the malicious print/scan operation) rather than being a fully autonomous remote exploit. The flaws are unauthenticated per the vendor CVSS vector (PR:N), impact varies depending on which bundled sub-vulnerability is triggered, and no public exploit identified at time of analysis.
Out-of-bounds write flaws in HPLIP (HP Linux Imaging and Printing Software) can corrupt memory when a user processes attacker-influenced input such as a crafted print job, a malicious device or network response, or a handled file, with the affected product confirmed by HP and documented in advisory HPSBPI04151. No authentication is required to reach the vulnerable components, but exploitation depends on mandatory user interaction and on hosts that actually have HPLIP installed and in active printing or scanning use. Worst-case impact spans remote code execution, privilege escalation, denial of service, information disclosure, and unauthorized file modification; no public exploit code or confirmed active exploitation was identified at time of analysis.
Denial of service in HP's HPLIP (HP Linux Imaging and Printing Software) printing stack is reachable when a physically-present attacker supplies specially crafted input that triggers a CWE-191 integer underflow, crashing or hanging affected components; the scored CVSS:3.1 vector (AV:P/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) limits impact to availability only, with no confidentiality or integrity loss. The physical attack vector (direct hardware/USB or local physical access) is the dominant gating factor and rules out remote or network-based exploitation, and no public exploit has been identified at time of analysis. HP has stated that it identified and remediated the underlying issues, so a vendor fix is available per advisory hpsbpi04151, though the specific affected and fixed version ranges are not enumerated here and must be confirmed against that bulletin. Overall this is a genuine but low-priority issue: real availability impact, but exploitation requires an attacker to already have hands on the machine.
Denial of service in HP Linux Imaging and Printing Software (HPLIP) can be triggered by a physically present attacker who supplies crafted input via a local device or print/scan job, exploiting improper array index validation (CWE-129). Although HP's advisory bundles several vulnerabilities that could potentially enable a broader range of impacts, the specific vector for this CVE limits the effect to availability (system crash or service disruption) with no confidentiality or integrity impact. No public exploit code or active exploitation has been identified at time of analysis, and the primary prerequisite is physical access to the target system.
Command injection (CWE-78) in HP's HPLIP (HP Linux Imaging and Printing) software enables an unauthenticated local user to execute commands or modify files with high integrity impact (VI:H) after active user interaction, matching HP's CVSS 4.0 score of 6.8 (AV:L/AC:L/PR:N/UI:A/VC:L/VI:H/VA:L) and the independent CVSS 3.1 assessment (AV:L/AC:L/PR:N/UI:R/C:L/I:H/A:L). The HP security bulletin HPSBPI04151 bundles this issue with other externally reported HPLIP flaws that could lead to remote code execution, privilege escalation, denial of service, or information disclosure, but the exact vulnerable component is not disclosed. No public exploit code or CISA KEV entry is identified at time of analysis, and the local vector plus mandatory user interaction prevents triggering without a user processing attacker-supplied input.
Local attackers with valid credentials on Linux systems running HPLIP can exploit symbolic-link handling flaws (CWE-61) in HPLIP components to read or modify arbitrary files, as described in HP security bulletin HPSBPI04151. This CVE is one of multiple issues remediated by HP in HPLIP and is assessed as a moderate, locally-scoped issue (CVSS 3.1: AV:L/AC:L/PR:L/UI:N, limited confidentiality/integrity impact) rather than an urgent priority, despite the broader impact list in the description; no public exploit code or CISA KEV active exploitation has been identified at time of analysis. Exploitation requires local access and a vulnerable HPLIP component that follows attacker-controllable symlinks at a predictable path, limiting impact to unauthorized file read/modification.
