Heap-based buffer overflow in libsolv's repo_add_solv() function enables a remote unauthenticated attacker to crash the parsing process by delivering a specially crafted .solv repository metadata file containing negative values in the maxsize or allsize header fields. The malformed values bypass allocation sizing logic, producing an undersized heap buffer that is subsequently written past its bounds, yielding a denial of service. No public exploit identified at time of analysis; however, an upstream fix has been submitted via openSUSE/libsolv GitHub PR #617, and Red Hat has acknowledged the issue via a dedicated security advisory.
Stack-based buffer overflow in libsolv's Debian metadata parser allows remote, unauthenticated attackers to cause a denial of service by serving maliciously crafted Debian repository metadata containing SHA384 or SHA512 checksum tags. The root cause, confirmed by the GitHub PR #616 diff, is a statically allocated 65-byte stack buffer in `ext/repo_deb.c` sized only for SHA256 digests, which is overflowed by the larger SHA384 (96 hex chars) and SHA512 (128 hex chars) values. No active exploitation has been confirmed (not in CISA KEV) and no public exploit code has been identified at time of analysis; an upstream fix is available as an open pull request.
A flaw was found in the python-cryptography package. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity.
A flaw was found in m2crypto. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
The collection remote for pulp_ansible stores tokens in plaintext instead of using pulp's encrypted field and exposes them in read/write mode via the API () instead of marking it as write only. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity. Public exploit code available and no vendor patch available.
