CVE-2022-1451 (https://huntr.dev/bounties/229a2e0d-9e5c-402f-9a24-57fa2eb1aaa7):
https://github.com/radareorg/radare2/commit/0927ed3ae99444e7b47b84e43118deb10fe37529

Out-of-bounds Read in r_bin_java_constant_value_attr_new function in GitHub repository radareorg/radare2 prior to 5.7.0. The bug causes the program reads data past the end 2f the intented buffer. Typically, this can allow attackers to read sensitive information from other memory locations or cause a crash. More details see [CWE-125: Out-of-bounds read](https://cwe.mitre.org/data/definitions/125.html).

CVE-2022-1452 (https://huntr.dev/bounties/c8f4c2de-7d96-4ad4-857a-c099effca2d6):
https://github.com/radareorg/radare2/commit/ecc44b6a2f18ee70ac133365de0e509d26d5e168

Out-of-bounds Read in r_bin_java_bootstrap_methods_attr_new function in GitHub repository radareorg/radare2 prior to 5.7.0. The bug causes the program reads data past the end 2f the intented buffer. Typically, this can allow attackers to read sensitive information from other memory locations or cause a crash. More details see [CWE-125: Out-of-bounds read](https://cwe.mitre.org/data/definitions/125.html).

CVE-2022-1444 (https://huntr.dev/bounties/b438a940-f8a4-4872-b030-59bdd1ab72aa):
https://github.com/radareorg/radare2/commit/14189710859c27981adb4c2c2aed2863c1859ec5

heap-use-after-free in GitHub repository radareorg/radare2 prior to 5.7.0. This vulnerability is capable of inducing denial of service.

CVE-2022-1649 (https://github.com/radareorg/radare2/commit/a5aafb99c3965259c84ddcf45a91144bf7eb4cf1):
https://huntr.dev/bounties/c07e4918-cf86-4d2e-8969-5fb63575b449

Null pointer dereference in libr/bin/format/mach0/mach0.c in radareorg/radare2 in GitHub repository radareorg/radare2 prior to 5.7.0. It is likely to be exploitable. For more general description of heap buffer overflow, see [CWE](https://cwe.mitre.org/data/definitions/476.html).

This is obviously not a buffer overflow, but a null pointer
dereference DoS.

CVE-2022-34520 (https://github.com/radareorg/radare2/issues/20354):

Radare2 v5.7.2 was discovered to contain a NULL pointer dereference via the function r_bin_file_xtr_load_buffer at bin/bfile.c. This vulnerability allows attackers to cause a Denial of Service (DOS) via a crafted binary file.

CVE-2022-34502 (https://github.com/radareorg/radare2/issues/20336):

Radare2 v5.7.0 was discovered to contain a heap buffer overflow via the function consume_encoded_name_new at format/wasm/wasm.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted binary file.

Also fixed in 5.7.4.

[Comment 8 John Helmert III 2022-12-11 00:07:57 UTC]

Tree is clean.
