Threats
Impact
Important
A flaw was found in libpng, a library used for processing PNG (Portable Network Graphics) image files. This vulnerability arises from improper memory management where a heap-allocated buffer is aliased between internal data structures. When specific functions are called, a freed memory region can still be referenced, leading to a use-after-free condition. An attacker could potentially exploit this to achieve arbitrary code execution or cause a denial of service.

Impact

A flaw was found in libpng. A remote attacker could exploit an out-of-bounds read and write vulnerability in the ARM/AArch64 Neon-optimized palette expansion path. This occurs when processing a final partial chunk of 8-bit paletted rows without verifying sufficient input pixels, leading to dereferencing pointers before the start of the row buffer and writing expanded pixel data to underflowed positions. This flaw can result in information disclosure and denial of service.

Threats
Impact
Important
A flaw was found in libpng, a library used for processing PNG (Portable Network Graphics) image files. This vulnerability arises from improper memory management where a heap-allocated buffer is aliased between internal data structures. When specific functions are called, a freed memory region can still be referenced, leading to a use-after-free condition. An attacker could potentially exploit this to achieve arbitrary code execution or cause a denial of service.

Threats
Impact
Moderate
A flaw was found in libpng. A remote attacker could exploit an out-of-bounds read and write vulnerability in the ARM/AArch64 Neon-optimized palette expansion path. This occurs when processing a final partial chunk of 8-bit paletted rows without verifying sufficient input pixels, leading to dereferencing pointers before the start of the row buffer and writing expanded pixel data to underflowed positions. This flaw can result in information disclosure and denial of service.

Threats
Impact
Important
A flaw was found in libpng, a library used for processing PNG (Portable Network Graphics) image files. This vulnerability arises from improper memory management where a heap-allocated buffer is aliased between internal data structures. When specific functions are called, a freed memory region can still be referenced, leading to a use-after-free condition. An attacker could potentially exploit this to achieve arbitrary code execution or cause a denial of service.

Threats
Impact
Moderate
A flaw was found in libpng. A remote attacker could exploit an out-of-bounds read and write vulnerability in the ARM/AArch64 Neon-optimized palette expansion path. This occurs when processing a final partial chunk of 8-bit paletted rows without verifying sufficient input pixels, leading to dereferencing pointers before the start of the row buffer and writing expanded pixel data to underflowed positions. This flaw can result in information disclosure and denial of service.

Threats
Impact
Important
A flaw was found in libpng, a library used for processing PNG (Portable Network Graphics) image files. This vulnerability arises from improper memory management where a heap-allocated buffer is aliased between internal data structures. When specific functions are called, a freed memory region can still be referenced, leading to a use-after-free condition. An attacker could potentially exploit this to achieve arbitrary code execution or cause a denial of service.

Threats
Impact
Moderate
A flaw was found in libpng. A remote attacker could exploit an out-of-bounds read and write vulnerability in the ARM/AArch64 Neon-optimized palette expansion path. This occurs when processing a final partial chunk of 8-bit paletted rows without verifying sufficient input pixels, leading to dereferencing pointers before the start of the row buffer and writing expanded pixel data to underflowed positions. This flaw can result in information disclosure and denial of service.

Threats
Impact
Important
A flaw was found in libpng, a library used for processing PNG (Portable Network Graphics) image files. This vulnerability arises from improper memory management where a heap-allocated buffer is aliased between internal data structures. When specific functions are called, a freed memory region can still be referenced, leading to a use-after-free condition. An attacker could potentially exploit this to achieve arbitrary code execution or cause a denial of service.

A flaw was found in libpng. A remote attacker could exploit an out-of-bounds read and write vulnerability in the ARM/AArch64 Neon-optimized palette expansion path. This occurs when processing a final partial chunk of 8-bit paletted rows without verifying sufficient input pixels, leading to dereferencing pointers before the start of the row buffer and writing expanded pixel data to underflowed positions. This flaw can result in information disclosure and denial of service.

A flaw was found in Firefox and Thunderbird. The Mozilla Foundation's Security Advisory describes the following issue: Memory safety bugs present in Firefox ESR 140.9.0, Thunderbird ESR 140.9.0, Firefox 149.0.1 and Thunderbird 149.0.1. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code.

Threats
Impact
Important
A flaw was found in libpng, a library used for processing PNG (Portable Network Graphics) image files. This vulnerability arises from improper memory management where a heap-allocated buffer is aliased between internal data structures. When specific functions are called, a freed memory region can still be referenced, leading to a use-after-free condition. An attacker could potentially exploit this to achieve arbitrary code execution or cause a denial of service.

Threats
Impact
Moderate
A flaw was found in libpng. A remote attacker could exploit an out-of-bounds read and write vulnerability in the ARM/AArch64 Neon-optimized palette expansion path. This occurs when processing a final partial chunk of 8-bit paletted rows without verifying sufficient input pixels, leading to dereferencing pointers before the start of the row buffer and writing expanded pixel data to underflowed positions. This flaw can result in information disclosure and denial of service.

Threats
Impact
Important
A flaw was found in libpng, a library used for processing PNG (Portable Network Graphics) image files. This vulnerability arises from improper memory management where a heap-allocated buffer is aliased between internal data structures. When specific functions are called, a freed memory region can still be referenced, leading to a use-after-free condition. An attacker could potentially exploit this to achieve arbitrary code execution or cause a denial of service.

Threats
Impact
Moderate
A flaw was found in libpng. A remote attacker could exploit an out-of-bounds read and write vulnerability in the ARM/AArch64 Neon-optimized palette expansion path. This occurs when processing a final partial chunk of 8-bit paletted rows without verifying sufficient input pixels, leading to dereferencing pointers before the start of the row buffer and writing expanded pixel data to underflowed positions. This flaw can result in information disclosure and denial of service.

Threats
Impact
Important
A flaw was found in libpng, a library used for processing PNG (Portable Network Graphics) image files. This vulnerability arises from improper memory management where a heap-allocated buffer is aliased between internal data structures. When specific functions are called, a freed memory region can still be referenced, leading to a use-after-free condition. An attacker could potentially exploit this to achieve arbitrary code execution or cause a denial of service.

Threats
Impact
Moderate
A flaw was found in libpng. A remote attacker could exploit an out-of-bounds read and write vulnerability in the ARM/AArch64 Neon-optimized palette expansion path. This occurs when processing a final partial chunk of 8-bit paletted rows without verifying sufficient input pixels, leading to dereferencing pointers before the start of the row buffer and writing expanded pixel data to underflowed positions. This flaw can result in information disclosure and denial of service.
