postgresql: integer overflow can cause an undersized allocation and an out-of-bounds write

A flaw was found in PostgreSQL. An integer overflow in multiple server features allows an unprivileged database user to cause an undersized memory allocation that leads to an out-of-bounds write. This issue allows an attacker to execute arbitrary code as the operating system user running the...

Use After Free

Overview Affected versions of this package are vulnerable to Use After Free in the Oj::Parser when operating in SAJ mode with object keys of 35 bytes or longer. An attacker can cause a segmentation fault by triggering garbage collection within a callback, leading to use of a freed memory pointer...

GHSA-M578-W5VF-RFCM Oj: Use-After-Free in Oj::Parser SAJ Long Key Callback

Summary Oj::Parser in SAJ mode does not protect cached object keys ≥ 35 bytes from garbage collection. A Ruby callback that triggers GC inside hashend can cause the key string to be reclaimed while the C parser still holds a pointer to it. The subsequent access to the freed string VALUE results i...

Oj: Use-After-Free in Oj::Parser SAJ Long Key Callback

Summary Oj::Parser in SAJ mode does not protect cached object keys ≥ 35 bytes from garbage collection. A Ruby callback that triggers GC inside hashend can cause the key string to be reclaimed while the C parser still holds a pointer to it. The subsequent access to the freed string VALUE results i...

Oj: Use-After-Free in Oj::Parser array_class/hash_class GC Marking

Summary Oj::Parser in usual mode does not mark arrayclass and hashclass references during garbage collection. If GC runs after the class is assigned but before a parse, the class object is reclaimed, leaving the parser holding a dangling VALUE. The subsequent parse call dereferences the freed...

Astra Linux – Vulnerability in binutils

A issue was discovered in the Binary File Descriptor BFD library also known as libbfd, as distributed in GNU Binutils 2.32. It is an integer overflow that leads to a segmentation fault in bfddwarf2findnearestline in dwarf2.c, as demonstrated by the nm tool...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Net: Properly handles tunneled traffic when using GSO fallback for IPV6CSUM. NETIFFIPV6CSUM only indicates support for packet checksum offloading without IPv6 extension headers. Packets with extension headers must rely on...

Astra Linux – Vulnerability in binutils

A issue was discovered in the Binary File Descriptor BFD library also known as libbfd, as distributed in GNU Binutils 2.31. An invalid memory address dereference was identified in the readreloc function in reloc.c. This vulnerability causes a segmentation fault and results in the crash of the...

Astra Linux – Vulnerability in cjson

It has been discovered that cJSON v1.7.16 contains a segmentation violation due to the use of the cJSONInsertItemInArray function in the cJSON.c library...

Astra Linux – Vulnerability in TIF format

A segmentation fault flaw was discovered in libtiff, which can be triggered by passing a crafted TIF file to the TIFFReadRGBATileExt API. This flaw allows a remote attacker to cause a heap buffer overflow, resulting in a denial of service...
