CVE-2010-1797 is a critical memory corruption vulnerability in Apple Iphone Os, published on 16 Aug 2010. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link. ### Official description Multiple stack-based buffer overflows in the cff_decoder_parse_charstrings function in the CFF Type2 CharStrings interpreter in cff/cffgload.c in FreeType before 2.4.2, as used in Apple iOS before 4.0.2 on the iPhone and iPod touch and before 3.2.2 on the iPad, allow remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via crafted CFF opcodes in embedded fonts in a PDF document, as demonstrated by JailbreakMe. NOTE: some of these details are obtained from third party information. Weakness: CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) ## Which versions are affected by CVE-2010-1797?

What it is: CVE-2010-1797 is a critical memory corruption vulnerability in Apple Iphone Os, published on 16 Aug 2010. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link. Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2010-1797 exists. Affected product: Apple Iphone Os. No package-level version data is available, so check the vendor advisory linked from the reference page. Task: 1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies. 2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
