Denial of Service (DoS)

Overview ultimate-sitemap-parser is an A performant library for parsing and crawling sitemaps Affected versions of this package are vulnerable to Denial of Service DoS through the gunzip process. An attacker can exhaust system memory or crash the application by serving a specially crafted...

GHSA-8823-QG2X-PV9F Ultimate Sitemap Parser (USP): Gzip Decompression Bomb Bypasses Sitemap Size Limit

Gzip Decompression Bomb Bypasses Sitemap Size Limit Summary ultimate-sitemap-parser enforces a 100 MiB size limit on sitemap responses, but applies it only to the compressed bytes received over the network. When a .gz sitemap is fetched, usp/helpers.py:239 calls gziplib.decompressdata with no...

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...

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...

Use After Free

Overview Affected versions of this package are vulnerable to Use After Free in the parsermark. An attacker can cause a segmentation fault and potentially crash the application by triggering garbage collection after assigning a custom class to arrayclass or hashclass and before parsing, leading to...

Oj: Negative-Size memcpy in Oj::Parser create_id Attribute Handling

Summary Oj::Parserparse in usual mode with createid enabled is vulnerable to heap corruption via a negative-size memcpy. When a JSON object key is exactly 65,535 bytes long, an integer truncation in formattr usual.c:63 converts the length to -1 before passing it to memcpy. This causes memcpy to...

CVE-2026-48715

radvd is a router advertisement daemon for IPv6. Prior to version 2.21, the radvdump utility shipped with radvd contains a stack buffer overflow in the Route Information option parser. When processing a crafted ICMPv6 Router Advertisement, printff copies up to 2032 bytes from attacker-controlled...

GHSA-Q2GM-54R6-8FWM Oj: Use-After-Free in Oj::Parser SAJ Callback via Input Mutation

Summary Oj::Parserparse is vulnerable to a heap use-after-free when a SAJ/SAJ2 callback mutates the input JSON string during parsing. The C engine holds a raw const byte pointer into the Ruby string's internal buffer. If a callback e.g. hashstart resizes the string — for example by calling...

Oj: Use-After-Free in Oj::Parser Symbol Key Cache Toggle

Summary Disabling symbolkeys on a reused Oj::Parser instance triggers a heap use-after-free. When symbolkeys is toggled from true to false, optsymbolkeysset frees the internal key cache cachefree but does not clear the pointer. The next parse call reads from the freed cache via cacheintern,...

Summary Disabling symbolkeys on a reused Oj::Parser instance triggers a heap use-after-free. When symbolkeys is toggled from true to false, optsymbolkeysset frees the internal key cache cachefree but does not clear the pointer. The next parse call reads from the freed cache via cacheintern,...

Use After Free

Overview Affected versions of this package are vulnerable to Use After Free in the optsymbolkeysset. An attacker can cause the application to read from freed memory by toggling the symbolkeys option from true to false on a reused parser instance and then invoking the parse method. Remediation...

radvd is a router advertisement daemon for IPv6. Prior to version 2.21, the "radvdump" utility shipped with radvd contains a stack buffer overflow in the Route Information option parser. When processing a crafted ICMPv6 Router Advertisement, "printff" copies up to 2032 bytes from...

CVE-2026-49293

CVE-2026-49293 affects js-toml up to v1.1.0. The parsing of hexadecimal/octal/binary integer literals uses a hand-written parseBigInt loop that multiplies the BigInt accumulator by the radix for every digit, yielding an O(n^2) time complexity in the length of the literal. A single TOML document c...

CVE-2026-49293

js-toml is a TOML parser for JavaScript, fully compliant with the TOML 1.0.0 Spec. Versions up to and including 1.1.0 parse hexadecimal / octal / binary integer literals via a hand-written parseBigInt loop that multiplies a BigInt accumulator by the radix once per input digit. Each iteration...
